Does a lot of mastubation affect my sexual performance ??
I'm 18 years old and I've been masturbating for 4 years, and I feel that masturbation has affected badly on me, when I masturbate I ejaculate very fast, I can ejaculate after 5 sec from touching my penis, especially while watching porn, I just get so aroused I can't control it and let it go, I think the only reason for that is my excessive masturbation, I masturbate 2 hours daily and I use stop and go method, when I'm close to cum I stop and after minute I go again and so on, before a month a girl gave my my first blowjob and I cum after 30 sec, I didn't even had fun doing it cause I ejaculated very fast, and the only logical reason for this is my masturbation,the girl is coming back and she want to have sex with me again and I don't want to disappoint her again so what do you think and how to last longer in bed ???
