1. For increasing male performance, we don't want men to charge the sympathetic nervous system that causes early ejaculation; instead, we want a high level of bioeletricity in the parasympathetic nervous system to hold a long and hard erection.
2. For accelerating female orgasmic response, we want women to charge both the sympathetic and parasympathetic nervous systems. The reasons are: the sympathetic division fires up the orgasmic power surge to drive the contraction of the uterus while the parasympathetic division is responsible for engorgement and lubrication of the vagina to prevent intercourse pain.
