I sort of doubt that you can. Men are all over the scale in this matter. Some do not leak at all, some a little, and some a lot. I know how you feel because I, too, am a leaker. It seems as though there is always some leakage from my dick. With the least bit of excitement, the flood gates are really opened. You gotta just lean to live with it. Look on the bright side, it shows sex partners you're really turned on, it's a great lubricant and a LOT of sex partners enjoy eating it.
