This all started when I was 16, when my libido was on fire(teens and their hormones, amirite?), I masturbated around 2 to 3 times a day normally, without using any "death grip" or something like that. I started using porn around that age, too. I adopted this habit because I was constantly being rejected by girls and they all looked at me like I was some kind of spider they saw in the bathtub. I also got to a point where I started to masturbate while flaccid(which i didn't know it was possible) so I think that there's an extra issue here, I basically taught my brain to not have an erection... For years I used masturbation(occasionally with porn) to fill the void that rejection caused. I also noticed that, throughout the years, my sexual sensitivity was decreasing but what the hell, I was going to die alone so that's useless, right? As recent as two years ago, I started getting more and more attractive to the opposite sex(I don't know why, though, I always looked the same(until then) since I was 16, only with more facial hair), I started dating a chick and that's when I noticed that this was going to be a problem(too damn late, you idiot). My erections were awfully weak, to the point of not being able to penetrate. I went to an urologist and got a thorough examination but my penis is good, no permanent damage whatsoever, and he suggested that it's a hormonal issue. Nonetheless, I think that this was because of compulsive overestimulation and not because of porn(I normally fantasized about real girls). I've abstained from masturbation(36 days and counting) because I can't get decent erections with anything. I've become too desensitized to sexual stuff, even though I can get minimally aroused with a partner. So my question is: how do I regain sensitivity after all this time? I know that it's gonna take a while but is there any additional help I can get?
