Hey BB ..
This'll be a -huge- wall of text, but, ya know .. "teach a person to fish" ... etc ...
Like everyone in a developed country, and that watch a lot of adult entertainment, and who Penis Enlargement, ... you've got about three different issues piling up and any or all of them could be your problem ..
One is like other people are saying ... the adult entertainment has been incrementally raising your Erotic Threshold to a level that you don't encounter in real life.
Probably like most when you were younger .. just a chick in a bikini ... or a bra or jeans advert on television would be enough to do it for you, much less an actual chick playing with your cock.
But you aren't encountering multiple superhot lipstick lesbians who warm themselves up for you and then want you in all of their asses, ... or chicks getting jizzed by 100 guys, or cramming soda cans or bats up x,y,z while tied to sharks with laser beams.. or whatever .. during the course of your actual day.
I had a long post about this around (wow, long time) 7 or 8 years ago.. but can't find it on the search. That's the gist though ^ ... you're probably 'poisoning' your ability to get excited at normal stuff with wild things you don't -physically- have access to.
You definitely should go off of -all- adult entertainment while addressing the other issues I'll mention in a second.. and then -
After- you're better .. you can maybe use very specific adult entertainment if you need to: adult entertainment that's boy/girl-Only (or whatever you're specifically into) ... and only the stuff that features chicks with -your- chick's body type (same race, same tit size, same holes being used, no 5 other girls banging her with strapons
etc .. )
Two, .. you should definitely look into doing Pthalate Detox. Pthalates are plastics-softeners (and penis-softeners) used in everything everywhere that leech into the foods and water, accumulate in your body, and the whole time they're acting like Estrogen. This stuff is so bad in the general environment that frogs could be killed off forever and baby boys are being born with smaller and smaller penises, and like dolls more, and like war/sports less. It's a wonder we even have dicks, much less expect them to work.
Check out this
http://www.peak-health-now.com/pthalates.html as something to get you started. Found it just now to save me some typing, seems to cover the key concepts.
Besides avoiding Pthalates whenever possible, you'll want to increase your body's production of Glutathione. That's a sticky sulfur-based enzyme your body makes (when it;s allowed to) which is your main detoxifying process for stuff like this. You'll want to get organic sulfur (eggs - with the yolks not overcooked all to hell - are awesome for it), and Zinc (anything but 'oxide'), and Selenomethionine, and N-Acetylcysteine (NAC). Those are the main constituents for Glutathione. Don't try to 'buy it' as a single product, that's a fortune and doesn't work well. Just feed your body the stuff I listed which it needs to produce it.
Also if you want to go nuts (ie ... get super healthy at multiple levels) I'd also add:
1) Optimox IODORAL (iodine) in the 12.5mg size .. and after taking it for several days, begin a Bromine/Fluoride Detox by taking one of them every eight hours (4 per day, spaced out) for a week. You will probably get a RAGING headache from this for a couple of days as Bromine gets forced out of your brain, etc, .. and then feel preposterously better afterwards. Like, crazy-higher energy and likely an extra degree F of body heat. Sufficient Iodine (at these levels, not the RDI figure that's 34 times lower) is used for more stuff than I'd type here. I'd add a link for it but you'll learn more on the subject if you look it up yourself. I do recommend the 180 tab bottle so it's not running out so fast, especially with a 4/day detox. And if you, or anyone, wants to, you can PM me and I'll see about emailing you a cutting-edge interview with Doctors Tennant and Starr about body energy systems and proper bio-voltages that's, to understate, Mind Expanding..
2) Magnesium (not 'oxide') .. at 2.7 mg per pound of body
weight. The 400mg usually recommended is great, if you're a girl. For guys, that can be too low and it's ironic that most guys taking it ..because they know they should .. are nonetheless chronically starved for it cos they're not getting enough.
3) Liposomal Vitamin C. -- That's Ascorbate that's been nano-encased in an emulsifying agent (so it can easily slip into your system and then easily into your cells.) It's crazy-better than normal Vitamin C, which itself is a detoxifying agent, (like people are taking LipoC for their general health and then going "Damn, where did my Leukemia go??")!! The stuff is kinda new and the few places selling it are charging a Lot, except for this guy
http://products.mercola.com/vitamin-c/ , and the stuff he has is Sunflower-based, not Soy, so no extra Estrogen issues either. You can also make your own, I do, but that's maybe too esoteric, and the result is a liquid that you can't haul around handy like these ^ caplets. Info about the stuff is all over the web.
Three, .. too much intense Penis Enlargement can damage your epithelial function and that can directly cause ED issues. The very tissues that produce the nitric acid that cause erections are harmed (temporarily, ... they'll' fix themselves eventually) but you can't keep Penis Enlargementing at that intensity if it's causing you erectile issues. Back off until it's better, then pay attention to look out for any unacceptable lowering of erection quality as you add intensity back into your workouts.
The nutrients I've listed already for other issues also help immensely with recovery from this sort of thing too.
Fourth bonus thing ... unless you're Acting In adult entertainment (and need to stay up while the director gives new blocking or cameras are rearranged) you shouldn't ever need any pharmaceutical erection drugs. If your epithelial cells are (temporarily) damaged, there's not a lot they could do anyway. -- But if you want to increase your reserve capacity for nitric oxide production, increase erection hardness, speed up recovery times, and even increase flaccid hang size, you might enjoy adding a nutrient-vasodilator to your diet like Arginine Alpha-Ketoglutarate. Like anything, you can pay waaay too much for it in the highly-advertised products, .. or you can get it in 250 gram kegs for like $20 per month. Great producer great price here

I'd say 'Hope that all helps', ... but i know it will, so ... enjoy banging things with your steel-hard banger
