I'm curious of the effect of ejaculating on mood, energy, metabolism, etc. I would say that after ejaculating my energy levels are low - an obvious downside. Does this mean Grok never masturbated? (It would be a waste of energy).
This is also what tantra teaches - to refrain from coming needlessly (but emphasizing that there should never be any guilt when you do masturbate), and training yourself to control your orgasms and maintain high energy levels by not coming every time you stimulate your penis.
In short, thoughts on 'primality' of masturbation?
