I have been with my fiancee for almost 8 years and he has always had a problem with Premature Ejaculation. He lasts anywhere from 20 seconds to 2 minutes. He usually lasts under a minute. This happens every time. He is 25 years old if that matters. We have already tried changing frequency of sex.

I’ve been having this problem for a while, this is quite embarassing and i want to stop these problems any way i can. I am still in my late teens, so i don’t think I should be having this problem. Does masturbating alot cause premature ejaculation. If so then how long should i wait to masturbate and how often is normal..also are there anything i can do to keep my penis from losing an errection like diets or exercise, i want to do this without visiting a doctor..
