Sir i'm 36 male, recently married. I'm unable to do intercourse as I loose erection too early and ejaculate early too. I have seen a sexologist and my testosterone and prolactin levels are normal too. I don't have diabetes or cholesterol issues. Doctor has suggested me some viagra and antidepressants. May I know what are the other tests can be done to check any other internal issues, I don't want to take this medicine as I have heard this have a lot of side effects. Please help me.
