So, I'm a 18 y/o male, with some experience now in sex and related stuff, and I have a huge problem. I've tried everything, but I CAN'T CUM! I don't enjoy sex, but I want it, I can only cum when I masturbate and I think the problem lies there. Furthermore, I can cum only when I compress my entire body like a stone and start wacking off like a maniac. It's really annoying, it's humiliating when I can't cum during sex although I can make my partners cum. I've tried various sex positions and I've been with attractive women, though it hasn't helped a lot. I just don't enjoy it, vaginal sex, handjobs, blowjobs, it's not enjoyable for me. PLEASE, I hope someone has the answer and that I'm not the only one. After all, there are 7fucking billion people on the planet...I can't be the first. P.S - Sorry for bad and unclear English, I'm not a native speaker.
