When I started having sex with my girlfriend when i was about 19, I used to ejaculate after like 25 to 35 mins, so she and i staeted to get worried, and now a year have passed and im facing the same thing, even most of the times i dont reach orgasm at all,,,, im very healthy i dont take any kind of drugs and i think the reason is becuz i used to masturbate almost daily when i was a teenager, so my penis got used to high stroking stimulations,,, so what should i do?
