According to Osho, brooding over past sex or fantasizing about future encounters dissipates the mind’s sex-energy through mere thinking, inflating tension and the urge for release. Living wholly in the present stops this leakage, lessens anxiety, and conserves sexual vitality, allowing it to remain integrated and move upward rather than being wasted in downward discharge.
If you keep thinking about sex before or later, you drain your inner battery; if you stay with the now, the battery stays full and calm.
