It is common understanding that over-indulgence in drink and drugs lead to ruin but it is uncommon for people to understand that over-indulgence in sex can lead to the same thing. Let that sexual energy build up inside you. Don’t dissipate that energy haphazardly because that energy is sensed by other people and draws them into you like a magnet. Being highly sexed (i.e. having sexual energy) but not giving in to any and all desires is the key to success.
Jung understood this, his faults notwithstanding. Sex should rarely be an end to itself, as feminists decry, it may be used on a spiritual path to greater things.
If you look at Taoist religion, it perhaps explains female hypergamy. Women are considered to have a near-infinite supply of energy (with which to cock-hop, if we lack morals) and can even sap a strong man’s strength (see: countless mythologies).
On a purely physical level, we understand acting upon sexuality depletes us, energy is lost, but the modern Progressive Party line dismisses yet another facet of reality. Certainly, indulgence is a good thing, when tempered with control and moderation, typically masculine virtues.
