I've been in a serious relationship for 10 years and I have been having problems with premature ejaculations and erections problems for about the last 2 years or so. I'm fine during foreplay but for some reason within a few minutes for intercourse I ejaculate prematurely. Sometimes my girlfriend says that my penis feels semi-erect. I never used to have any kind of problem like this and this is the only woman I've been with for the last 10 years. I'm completely attracted to her, so I know she's not the problem. I'm embarrassed to discuss with anyone but my girlfriend and luckily found this embarrassed. I'm hoping someone has a clue what's going on with me I'm only 30 years old and don't want this to be the end of my sex life. Please help!!
