Kinda old fag here I don't post much but read. Have you ever been with a girl you're not sexually compatible? Got a year with my gf. Love here, she's cute, nice tits, round ass, kinda fit, she does crossfit sometimes but I cannot get a hard on on her. Don't know why, if I do it lasts like 10 minutes and it's impossible for me the came with her, not sex nor oral sex. I can make her come with no issues, but I have to jerk off later. At the beggining I thought it was me, but when I jerk off I last longer. Also fuck another girl just to make sure it was me and I did improve my time. What can I do?

Stop masturbating for two weeks to regain sensitivity.

Lol, i have opposite problem - i can go on for hours straight, and believe me this is a problem.
