How can you last longer during sex without ejaculating so rapidly?

* When you feel yourself building up to the point when you are about to ejaculate, think about something that's not at all sexy. This might help a bit.

* I masturbate before I go to bed and this makes me last at least 20 minutes, and I still cum just as much. * Do kegel exercies! They help you control when to come and improve your orgasm.
