Many, if not most, men are just like you. They masturbate, or have sex multiple times, or force themselves to 'think' about something else while having sex.

What happens if you have intercourse again, within a few minutes of having an orgasm?

First, you need to find out if there is a medical problem. What is your age, other health issues, do you masturbate frequently? How often are you trying to have sex?
