Need more answers on this new issue

Yesterday my penis it was like a croissant or those glazed donuts but also my testicle not just penis. Meaning the chippy feel all over, and a bit shriveled of a look. Did not notice pain. Today skin started feeling not tons but you can see in photos. The chippy feeling hasn't went away today, and the head after I used masturbator this morning started bleeding developed 3 lines like scratches, in the pics only one is still visible. The head it reminds me how it looks so etines while still in the pump, like a bubbly patio path kind of texture, I see this sometimes when near the end of pumping sessions it goes away like 5-15 minutes after taking my penis out. Also when using my masturbator this morning almost the whole middle half, up to the bottom of the tip of my penis turned a very dark brown almost black color but not quite black like a very dark rubber band color. I stopped masturbating it went away almost instantly. I was horrified like is my dick gunna fall off etc. I'm very worried but out of all this the only 'painful' part was the penis head lines the testicles slightly painful like a dry feeling. I did put lotion all over before the gym which I didn't know we had, and it seems to be hydrating it quite a bit but not fully helping. Does anyone know what this all is?? How dangerous is it?

I'm gunna add to this a few nights ago I took a very very hot bath to help the fluid build up I was having, soaking my entire penis and balls in the bath extremely hot water for about 10-15 minutes, then just warm another 8-15 minutes. Could that hot water have dried me up somehow or contributed another way to this skin stuff???

Definitely way too long of a trapped blood. Dark brown ro dark black is an indicator of oxygen deficiency. Too long in the black can cause necrotic or tissue death. If you are not allergic or suffer from bleeding disorder to acetaminophen, drink the smaller doses of 70 to 80mg a day for the next 5 days. It's just to prevent blood clothing issue from manifesting.

I hope for your sake ,you didn’t cross whatever line I did,and never knew it. The best advice I can give is to stop doing this nonsense before you realize it’s too late. I’m 2.5 years in,and my regret is as strong as ever. This stuff can destroy your life. Period. I’m in the slowest recovery process ever, and there’s nothing I can do but pray. Thank god I’m still functional, but at the same time, every day is still absolute hell. Losing half the feeling to your junk is no game you want to play. I have an entire new set of rules my body is still trying to process as normal. Not sure I’ll ever get there, but dang I’m trying. Good luck.

Unfortunately, it's not PE. It's because of masturbation toy, or toys, in combo with over trapping the blood through constrictive means during the activity.

Perhaps.but I thought this started in another post from doing other stuff too.

Correct. The brother restarted his training, but what he reported was the formation of lymphatic fluid, or a buildup of fascia fluid because of very high pressure pumping. The constrictive blood flow is due to the pleasuring toy and the way it is used. There's also micro abrasion or tissue fissuring based on the description, and that may be from other things besides PE. We can only do so much to decipher information and provide simple resolutions without physically being there to examine closely.

I try to picture the rollers causing all this I can't picture it doing anything but the abrasions. The other stuff it doesn't seem possible. Last night I was using a sex toy again I took my penis out on the tip were two big black spots like spiders that shape kind of one was almost the whole length of my penis head (they were on the head) width maybe a fifth of it then next to it that one was a little smaller. It scared the shit out of me, I stopped using the toy they went away fading away after a minute or less. I could also see minor vein visibility in my penis tip. I don't know how jelqing could cause this unless I thought is it working blood UP into the penis head too much?? I don't even touch the head when I jelq but I'm afraid

Rollers definitely cause abrasive damages, such as small fissures and cracks in the sensitive skin layers. Mostly around the glans.

The spider-shape is the bloody blister, and the spider-leg shape is the capillaries surrounding the blister. The blisters are the pointa of injury, or the impact event. Recall what happened. It's not just constrictive from jelqing or pumping. It may be the roller doing light damages before, where the wheels pinched the skin and you didn't see it until blood blister formed from excessive pressure. But try to recall to the best that you can.

When the dark colors go away in a few minutes, that means the blood trapped in the engorged state was too long. When oxygen is deprived in the blood vessels, the blood goes from a healthy red-pink to purple, brown, then black. Black means blood cell deaths. Same for surround cells in healthy tissues if the oxygen is deprived for too long. Think of hyperthermia, where skin and muscle tissues died from frozen tissues, because the blood cannot carry sufficient oxygen to keep those areas alive.

Just do be careful on low long you keep the blood from being trapped in the penis, under specific pressures. High pressures can rupture capillaries.

The black spots they went away pretty quickly but like faded away. It happened using a sex toy like a flesh light I have on full vibration and contaction the rubber sleeve is like fleshlight but just white circle shaped with bumps in it not a vagina. I stand up put it against counter or wall and normal sex position it. The rubber goes it sideways alot it's shitty quality it goes in while I'm using it I'll just keep going I can tell by feeling my penis tip is bent like bent over and I just keep going. I'll take it out like holy fuck I see the veins in my fuckin penis tip to an extent then the black shit. It all fades away I just estimate within about a minute for full fading. It's very scary. I do not see any today I did my jelq no pain nothing new. But I'm extremely afraid I read about necrosis gangrene all that it pisses me off so bad all I'm doing is 20 minutes of jelqing not extreme jelqing and 20min pumping a day if it goes above 15hg I let the air out immediately. I don't know what to do I'm very worried about the tip the rest of stuff minimal since skin is healing up and Google says hot water skin burns first degree, which is prob what I had, go away on 3-7 days. But then the jelq I have never heard jelqing causing cracked skin even on the testicles?? That's also why I hope it's from the hot bath I took soaked them nights ago

Whatever on earth you’re doing, this is a clear sign to stop. You’re lucky you have a sign.
What did you do what exactly happened and I'm very sorry to hear that. Me I'm keeping up my routine long as I don't see the exercises causing anything, the sex toys I do see doing it so I'm throwing them out will buy better ones where the rubber stays in place.

How long will this issue resolve do you think, the black spot issue, since I stop seeing it for it to be fully healed or at least close?

Playing with fire. But do what you like I guess.
What happened to yours? I just don't want to give up I am noticing very good girth gains and even imo medium length gains. I think the sex toy had a lot to do with it I was even putting it on floor laying down, cramming in because the sleeve on it is loose at some points, and laying in bath w it sideways jamming in against tub wall. I think and hope this is the main culprit for the black spots and I will never do again

well, to be short. I cant really feel it. It shrinks something fierce most of the day. No arousal or erections in the day anymore. I masturbate zero times a month, every month. Don’t pee right, don’t crap right.have no response when I kegel 99% of the time. Nothing is whatsoever the same anymore. No way out either. If you felt this one single day, youd give it up. But proceed as you will,cause this means nothing to anybody that hasn’t experienced it. lol.

It's the combination of constriction and the fleshlight movements deep inside while the blood is fully engorged. Very common. Just go easy with the toys without any constriction. Wash the toy well and sterilize it according to recommendation.

Don't use hot water to the point of 1st degree burn. That's a bit too hot. Just warm to hot compression like you're taking a nice hot shower. Not to the point of feeling like you're being scolded by hot water. 15 minutes of warm-hot compression, follows by 5 minutes of cool compression, and switch back to hot compression, and back to cool compression. Keep going as long as you have the time to move the blood in and out of the penis more quickly.

Jelqs, depending on how hard to pull the skin, can cause cracking in the skin layers. But that's too little to notice compared to what you described. What you're describing is impact of a pinched skin. That takes a lot of force.

Tyvm bro you all are huge blessings!!!! I threw away my sex toys stupidly I tried again to be careful a bit ago penis head only slightly started one thin.black.line but the brown band on my penis it's like rubber band.cokored.it. somewhat turned black but see through like the bottom half of my penis like see through black I massaged it gently it went away it is scary AF to me. I'm done w sex.toys at least 5-7 days I don't know if I.shoild blame pumping for any.of this I may toss that too idk

Is all this different than actual gangrene or necrosis? If I just cut some shit out like sex toys gone none for now, pumping I may too idk yet, will this stop happening? The black spider shit or black lines or see through black?

Yes. Gangrene is when you skin is opened and there is tissue death. Necrosis is when there is tissue death. Tissue death and broken capillaries are two different things. Tissue death is more severe. Broken or ruptured capillaries healed over the course of a few days to a few weeks. We break and rupture our capillaries all the time.

Oh man god bless you brother, you guys really could be urologists or some other kind of penis doctors. I did skip today's jelq I decided to just take at least 4 days off any P.E because you said pinched it definitely was feeling pinched it's just kind of hard to notice unless using sex toys. Today none at all. I guess maybe the jelq is pinching some then the pump maybe I shouldn't go 13-15hg stretches for 20 minutes. Either way just taking break now, ordered me an EZ jelq gets here in 7 days. Thank God it's something that heals in a few days I do feel a ton of relief today no jelq or masturbation that pinched feeling just hard to really notice it too much until using sex toys then yes it aggravated it like shit and would be so for up to hours.

Sheesh. I guess if you don’t take the hint now,you’ll have to later. None of that sounds real good.
I don't believe you can't do PE safely many people say they have even for years and gained inches in girth and or length. You just have to cut it I guess when shit looks terrible, unlike the gym it's usually strains etc once I did her iate my back 5-6 years ago deadlifting 140lbs setting the bar down sideways 3 weeks crawling to bathroom to piss. But it's rare. With PE very scary stuff seems extremely common, but again it's not gangrene or necrosis I did Google capillaries there just small blood vessels, so they looks scary yes no good but it's gunna heal within days already would say a bit over half way feeling to normal. It just must be that PE workouts require severe care, and attention to things, vs gym workouts. It's a much more sensitive and care needing process. I am very sorry to hear you got injured too it's a very scary thing to start seeing shit. God bless you brother

You did PE and the next morning woke up and it was gone? Why can't you tell us what happened

The best thing is to have a nice little read about the brother's issue here:

Is that the whole article?? Shit I've had that happen many times over pumping a bit more than usual the next day dick is smaller and a little numb. It's in recovery I don't think that's a serious issue at all that's just my opinion if the numbness is mild and no bruising. That's very normal to me.

To me ,it seems like a combination of nerve shrinkage,and some weird stinging blockage in my rectum when I kegel. But it’s all over the place really. It’s still good size at times. But a lot of what I should feel isn’t there anymore. And some of what I feel, no one should ever have to feel. You couldn’t understand ever unless you end up this way. Nor would I expect anybody too. Cause I don’t either.

It'll probably fully heal over more time. So the doctors said diagnosis is nerve shrinkage?

Yeah. Highly doubtful. And I said “to me” it feels like nerve shrinkage. Doctors didn’t say anything, cause this is beyond anything theyve ever tried to figure out.
Should fully heal over up to years Google says. I have faith.

Well, im basically a totally different being now from this. I don’t see things magically going back normal ever again. Sorry, google AI
I don't use AI as i am petrified, by the the way, we can use this coming up quick in homeless all areas and but like the mark of the beast, I will never take it

I googled what is more likely to cause ruptured penis capillaries, which is what I believe mr old lively said the spider things I had were, penis pumping or jelqing. I assumed pump because I never touch my penis head jelqing and that's exactly what Google says pumping is more likely. Anyone think it's right?

Also I been at what I consider about 100% healed about two days now still no PE yet waiting for ez jelq to get here. But fuck I might give up the pumping I do think it played a role in the spider things I saw before the sex toy like making it fragile then that just blew them out

Capillary rupture is common on many fronts. For example, if you strain too hard while dropping a few long, hard turds into the toilet, you get ruptured capillaries in the form of weakened tissues that cannot contain something, and the sensitive blood vessels and other lower parts get impacted with it. Push harder, and the capillaries get compressed and burst. If you push too hard on a surface with your legs or arms, strain hard to get back up, or get released, you burst capillaries. Same for women and men who love to cross their legs all the time, you get capillaries pressurized, or spider veins.

In your case, you have too long of both pumping and sex toys, on top of jelqing. You are putting too much strain on the tissues and blood vessels. Need ease up on one of the three, or two of the three.

I was noticing near the end of my pumping sessions very hard to notice black coloring in parts of my penis tip but it never stood out the sex toy made it like surface and prob caused much more than just that may have. Tyvm for answers!!!! I might listen to what ppl on YouTube say and just don't go past 10hg pumping idk yet jelqing might be better anyways if I do end up just switching to that only and stretches sometimes

It's correct that -10inHg is pretty high up there. Most YouTube and pumping discussions don't explain why the -10inHg is dangerous, or going past that is very dangerous. But the truth or facts behind the -10inHg and higher also got muddled with other info that don't explain things out properly. However, we'll explain it here so you get the full information.

In the pump, and ONLY if you're erected, as the pressure goes past -5inHg, you're matching the internal pressure of your penis, with a +/- of 0.5 to 1inHg. As you go higher in pressure, you are actually increasing the internal pressure exponentially, and not linearly. What does that mean? It means for every 1 extra inHg in the vacuum, you are adding around 1.7 factor higher pressure than the internal pressure. The mathematical exponential normally follows a sequence of 1x, 2x, 4x, 8x, 16x, etc. Linearly is 1x, 2x, (3x for medical,) 4x, (5x for medical,) 6x, etc. Anything more than 1-to-1 is considered as exponential.

Let's break it down in a listing graphic to show the kinds of dangers our brothers are subjecting themselves to as they approach -10inHg, from a conservative perspective.

Pumping pressure (-inHg)Internal Pressure, Linear (-inHg)Internal Pressure, Factorial Exponential Curve (-inHg)Blood vessel expansion stress load (times of factor at 4.5inHg)
-4-4-40x
-5-5-5~1.1x
-6-6-10.22x
-7-7-11.9~2.6x
-8-8-13.6~3x
-9-9-15.33.4x
-10-10-17~3.8x
-11-11-18.7~4.2

Yes, the math is not exactly the same as general mathematics. We're talking about medical impact. When your blood vessels swell to 4x their natural size, the micro valves in the veins cannot prevent backflow, causing pressure to drop sharply. This is a venous leakage issue, or commonly known as ED. But for the capillaries, it doesn't take much. On average across the body, the capillaries rupture around 35mmHg to 55mmHg, or convert to around +1.4inHg to +2.2inHg, beyond the normal internal pressure load. Look carefully at the conservative table above.

Your capillaries ruptured at -10inHg, you're practically having a +17inHg internal pressure. That glans is under a massive load of pressure because it's the terminal point, the very end, where all the pressures accumulate. For those who have been pumping in a safer fashion, they have conditioned their blood vessels and skin tensions to take on the strains over time. For those who are new and start right off, they are endangering themselves to penile injuries beyond repair.

For those who wonder, "At what point does my blood vessel burst?" Well, it's around 50 to 70 inHg. It's hard to say since there are many kinds of blood vessels, from smaller to larger ones. For your penis, I can safely say around 60. How high a pumping pressure is that? Around -35inHg.

When you're having a blister, you have to ask yourself, what pressure do my penile skin layers separate? Well, around +1.3inHg. It's a way your body safeguards the internal areas. So, think about why your glans has blisters all the time as you increase pressure. Anything above -6 inHg with the pump increases the risk of a blister. This is why we condition the young skin, especially for the newbies, one little pressure at a time over a mount of time.

It's correct that -10inHg is pretty high up there. Most YouTube and pumping discussions don't explain why the -10inHg is dangerous, or going past that is very dangerous. But the truth or facts behind the -10inHg and higher also got muddled with other info that don't explain things out properly. However, we'll explain it here so you get the full information.

In the pump, and ONLY if you're erected, as the pressure goes past -5inHg, you're matching the internal pressure of your penis, with a +/- of 0.5 to 1inHg. As you go higher in pressure, you are actually increasing the internal pressure exponentially, and not linearly. What does that mean? It means for every 1 extra inHg in the vacuum, you are adding around 1.7 factor higher pressure than the internal pressure. The mathematical exponential normally follows a sequence of 1x, 2x, 4x, 8x, 16x, etc. Linearly is 1x, 2x, (3x for medical,) 4x, (5x for medical,) 6x, etc. Anything more than 1-to-1 is considered as exponential.

Let's break it down in a listing graphic to show the kinds of dangers our brothers are subjecting themselves to as they approach -10inHg, from a conservative perspective.

I use to think what you said, that peoples penis just get use to the strain over time because I use to do it with electric penis pumps months back I've done up to 3-3.5 month go around daily rarely missing a day 20min a day and had a few 2-3 months go arounds to w them they were the Amazon electric water penis pumps, for most of the cycles. No stretch and holds just would put it on the repeat mode worked up from mode 2-3 then to 4 (highest was always more 4) over about two weeks. After this period my penis felt fully tolerant to the 2-3 nodes, then for the fourth I also would say right around two weeks to tolerate it fully. I never one time got injured, bruised only the edema (if I'm even calling this the right thing, when it just stays very fat for a few hours or so after pumping). Now this manual pump I was just recently using I was doing stretch and holds trying to do them close to 15hg as possible w out going a I've when it did it maybe hold lightly, but usually just release the pressure and try again to hit 13-15hg to hold and stretch. Id stretch 30 seconds to around 4 minutes and do this my whole twenty minute session. This thing was causing much more severe shit than I've ever experienced on my life w pumps also I never did jelqing and pumping in same days. I feel like I liked those electric water pumps so much better I could just power it and lay in bath let it do its thing. Just stopped using them because not all of them are good a lot are pieces of shit break the first few uses only staying on mode 1 even if you try the buttons it wouldn't work past mode 1. But the handfuls I have had that worked amazingly they did die after 1.5-3 months tbose things none would last too long but the ones that lasted at least like 45 days did work better than any other pumps I ever had.
