In my pimply youth, I heard or read somewhere, I don't remember anymore, that sex was more enjoyable than fapping, because it involved physical exertion. I had a tip there: if I fap and do, say, squats at the same time, then the pleasure increases many times over. I tried it, and it was really cool.
For the next five years, I fell asleep just like that. Then, as an OC, I decided to fuck a real chick. By that point my dick was only hard when I was squatting, and even prank was sluggish without it, but I thought everything would be all right with a chick. I went to the salon, got alone with the whore, and I couldn't get it up.
Even when she tries unsuccessfully to put a condom on. So I, feeling like the last idiot, get off the bed and start squatting and jerking off. I have to hand it to the whore, she wasn't laughing, she was just watching with interest. I got up in a few seconds, climbed on top of her, and fell down again. So in the end I just had to jerk off in front of her. That's when I realized how fucked up I was. That was it.
