Get this book: The Multi-Orgasmic Man. By Mantak Chia.

It is a book on Taoist Chi-Kung. It teaches you how to have non-ejaculatory orgasms.

I'm dead serious guys! STOP LAUGHING!! This is true!!!

It also brings blood to "the area", constantly replenishing and replacing the oxygen to nourish the cells.

I know about this not because I have it, but because I Teach Martial Arts and I helped a friend overcome this problem(E.D.).
