This is going to be TMI for most people, so read at your own risk.
Basically my sexual functions failed me after physical trauma from a car accident, and I don't just mean erectiIe dysfunction or anything. The only thing that kind of makes me feel something is prostate stimulation, but it has to be pretty intense, not just a finger or anything. I used to do it solo with sex toys, but then I tried it with another man and it was a lot more enjoyable than a piece of silicon. I was never really attracted to men and I'm still not really turned on by the sight of any man. I chose to be gay since I can't really do anything else, including masturbation, and I'm a young guy. I'm pretty sure there are others like me.
