Well here I am, not a particularly active thread nowadays but I've been wanting to talk about this specific subject in detail so here I go. It's quite sad to see that some of Merek's posts are here, and that he's the reason for why this thread exists in the first place. Never figured out what happened to UnluckyXeplion either...
(NSFW, DON'T SAY I DIDN'T WARN YOU!!!)
Alright let me start by saying that before Invega, some time after undergoing puberty like most people, aside from physical changes like having a deeper voice and body hair growth, including pubic hair, I also developed the strong urge to have sex. Of course being quite young and single (which I still currently am for now, although I was in a relationship in high school), I had to release that sexual tension somehow, so of course I began to masturbate frequently. It's funny because I still remember the day I was horny as fuck and realized the overwhelming amount of pleasure I'd get from stroking my dick, and was even legit scared when I ejaculated for the first time in my life.
Long story short I continued doing it often for many years to come, (no pun intended), until the unfortunate day where I was injected with Invega arrived. Aside from the absolutely awful side effects like akathisia, anhedonhia, and severe insomnia to the point that it lasted for over 3 months, resulting in a stroke, there was one other particular set of side effects I had developed too. So like a week or so after getting injected with Invega, I decided to jack off one night before going to sleep, only to make the realization that regardless of how much I beat my dick or what I did or watched I could barely get an erection, let alone maintain it for more than a few seconds.
After furiously beating my dick for at least 5 minutes, probably closer to 10, I was finally able to maintain an erection and feel aroused long enough to have an orgasm. But I was immediately very concerned to realize I could no longer produce thick, white semen like I always could before. Instead all that came out were a few drops of clear, watery fluid. In a state of panic I decided to research if Invega could be what had caused this, and sure enough it was. By then I had felt very suicidal, hopeless, and depressed. At this point I stopped attempting to masturbate for a few weeks straight since aside from the inability to jizz I got little to no satisfaction anyways, definitely the longest I've gone without jacking off since I underwent puberty.
Eventually there were occasions where I'd attempt to masturbate again to see if I get erections more easily, and produce healthy looking semen once again. Over time I began noticing that it was becoming easier to feel aroused, and my semen was finally not only increasing in volume, but also coming out whiter and less runny each time. By this point I was finally starting to feel relieved and content that I was recovering sexually for once, since I had lost hope about ever recivering since I read about guys still suffering from antipsychotic-induced erectile dysfunction even several years after.
Fast forward to a week ago, my libido suddenly came rushing back A LOT, I once again feel a lot of pleasure from masturbating, can get random erections again pretty often, almost too often, and can maintain one for much longer as well. Not to mention my semen volume is basically back to normal and the color and consistency of it looks basically the same as it did before. The main issue I have now is that my penis shrunk by at least a solid inch, if not an inch and a half, even when fully erect, so I'm really hoping it eventually returns to it's original size some time sooner or later. Wasn't planning on being so descriptive or detailed about my situation with Invega but I eventually said fuck it, might as well as leave my experience here for other guys to read and hopefully feel more relieved that they'll most likely recover too.
