THE NATURE OF MORNING WOOD AND SUBTLE CULTIVATION OF PROSTATE

Morning wood is the exciting of postnatal yuan chi that is generated by sleep. The excititation is also consumption, though dreams are lucid.
Similar effect is present at states of near exhaustion. Body releases reserve of yuan chi. That gets trapped in erection. The intent is the after burn to finish the engaged activity. As such is an act in last resort and not way of partying.

Both action show separation of general state of well being and local exhuberation. There is a way to connect them.

Basic erection is characterized by concentration of excited postnatal yuan chi in penis and testicles. Such act is performed by means of bandha, the lock.
The lock is set in place by sexual palace (at pubic bone) (if minor erection) or contracted prostate (if grander erection).
If both places are systematicaly released when genital-only erection (example in morning upon awaking) is in place, this enables the connection of sexual energy to dan tien and true activating the sexual chakra. For then the sacrum/back of dan tien/ming men/kwa becomes the focal of sexual vibrancy.
Check of success at release is the lessening of erection as it was. This is immediate effect. However the long term effect is new locus of erection from sexual chakra/ming men/dan tien.

This may cause the impotence. More correctly, the impossibility of genital-only erection bias.
This also explains, why Hindus place sexual chakra at sacrum, and not at the point between anus and cocxys, nor at the perrineum, nor at the testicles, nor at tip op penis. They are explaining the end result, not the process.
