If you mean premature ejaculation, usually that refers to reaching climax within 1-2 min.
(Note that this may be normal early in a relationship, and will slow down as you get more comfortable with your partner.)
One method of slowing down is to "take care of yourself" once or twice beforehand. Or how about going for round two - or three.
Is it a problem for the women you have been with?
Some women view it as a testimonial to themselves - sort of "He finds me so hot that he can't control himself!"
Amber Smith (a super model and the original Wonder Bra model) made this statement on a radio show (Loveline).
