Hey IveADream, along with the Kegeling info above ^^ ... this is like a shotgun approach to anything else it could be. I do this occasionally so people can link out to it..
At 44, and doing high-volume routines, you might have additional issues which are pretty easy to test for.
--- You're drawing a coincide-ance/causality between the drop in EQ and your increase in intensity. It might not be anything more than that. You could take a seven to ten day break from PE .. still doing massage or heat or oils if you do those, but all lightly. Time-off for a full 'supercompensation' healing can be good occasionally anyways. If, after the time-off, the EQ issues seem better, there ya go .. just take a break once in a while.
There are two different complex erection mechanisms going on in a full tumescence of the erectile tissue. Through manual or erotic stimulation, the penal sphincter relaxes to allow a greater influx of blood... but that blood can still just run back out. This, by itself, will only get you a chubby. The second process has to work too. That's the production/release of nitric oxide from epithelial/endothelial cells within the corpus cavernosum. That diffuses into the smooth muscle cells lining the arteries, relaxing the vascular/trabecular smooth muscle and allows them to become fully engorged with blood, and THAT compresses the veins that drain blood back out... keeping blood filling in faster [at a higher pressure/rate] than it can drain back out.
If the epithelium etc cells are damaged, or their chemistry (neurokinins, VIP, PHydromax, etc) is interfered with by byproducts of the healing process ... they can't work right, so they can't expand right to trap the blood properly until they heal some.
There's also a 'minimal trigger energy' (parasympathetic innervation) for all of this happening the right way. If there's damage to the penile tissues, or impingement or damage to the lower spine, then the penis might not erect, ... or it might erect at first during foreplay or early sex but then give out and stop working.
Also, since this is a system, if you're not really emotionally 'into' the chick - or if mentally you're distracted or stressed out, this will also lower the innervation energy level.
Doing Kegels during a time-off is ok, as Kegels don't effect the epithelial/endothelial system of the penis the way high volume/high intensity PE could. That's the thing that the time-off would tend to fix. So if this does it, just back off until it's better, then pay attention to look out for any unacceptable lowering of erection quality as you add intensity/volume back into your workouts.
--- Have you stepped up your adult entertainment (if any) along with your step up in length routines? adult entertainment can incrementally raise your Erotic Threshold to a level that you do not 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 begging for and grabbing your cock.
But most of us aren't encountering multiple superhot lipstick lesbians who warm themselves up in front of you and then want you in all of their holes in no particular order, ... or chicks getting jizzed by 100 guys, or cramming soda cans or bats up x,y,z, while tied to monkey-piloted sharks with laser beams.. or whatever .. during the course of one's actual day.
I had a long post about this around 7 or 8 years ago.. but can't find it on the search. That's the gist though ^ ... adult entertainment can 'poison' one's ability to get excited at normal stuff with wild things that they don't -physically- have access to.
Just to
specifically test for epithelial/endothelial issues .. I might recommended that you keep your adult entertainment exposure (if any) the
same during the time-off. If the [physical] healing time fixes the problem, then your Erotic Threshold is probably ok. If not, you definitely should go off almost -all- adult entertainment for a while, and then you can go back with very specific
milder 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) so you'd be eroticizing yourself to things that you do actually encounter in real life.
--- By 44, you should definitely look into doing a 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 human male infants are being born with smaller and smaller penises, and later they 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
Detox From Pthalates to be Healthy and Slim! as something to get you started, seems to cover the key concepts. And also additionally Google Pthalate Detox yourself too.
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, somewhere, (eggs - with the yolks not overcooked all to hell - are awesome for it), and Zinc (anything but 'oxide'. ZMA might be a handy way to do it), and Selenomethionine, and N-Acetylcysteine (NAC). Those are the main constituents for Glutathione production. Don't try to 'buy it' as a single product, that costs a fortune and doesn't survive the gut very well. Just feed your body the stuff I listed and it will make its own.
--- Do you get enough sleep? Every hour of sleep less than 8 is supposed to cause a 20% drop in Testosterone. When someone is 24, that's not a big deal. At 44 it might be.
--- One more thing I was going to say and then forgot what it was. I know that's super helpful, lol.
--- Besides increasing your natural Testosterone .. and decreasing your Environmental Estrogens .. there are several things you can take for increases in both EQ and Libido. Without getting into stuff like Tribulus or Longifolia etc, which would be arguable, check out:
Korean Red Ginseng Root, 400mg 2x/day
Ginkgo Biloba Extract, "24/6 or higher", 120mg 2x/day
and
L-Citrulline Malate 2:1 Complex, 3grams 2x/day. (If you can find the
2:1 anymore, it's like it's disappearing .. but it's the "2" which does the heavy lifting, so any 1:1 product is half as good for these purposes.)
After a week or so, all of that should make you feel [and function] like 17 again ..
And if you still wanted to get into Test boosters (almost redundant by that point) check out -things- like
Test HD by MuscleTech at Bodybuilding.com! - Lowest prices on Test HD! , not it specifically, but it's a good demonstration of the right current ingredients in the right-ish proportions, so anything -like- it. [The Stinging Nettle could be higher].
