There is a concept about dry/multiple male orgasm. Most common idea is what by practicing clenching of ones pubococcygeus (PC) muscle just before a point when the process of ejacuation begins, a male can achieve orgasm without ejacuating or rest/refactory period. Question is: out of these options (or other which are not listed here) which is the true one? 1. Clenching PC muscle cancels the process of ejacuation and the inflow of rest/refactory chemicals, but not the orgasm. 2. The ejacuation still continues to the next available "outlet", i.e. the bludder?
