I've been practicing the art of "ejaculating up the spine" to rejuvenate myself with my sexual energy rather than waste it (David Deida - The Way of the Superior Man). Today I felt a tight buzzing all over my body during the practice, but then I had tightness in both my asshole & my lips for like 5-10 mins after. My lips were stiffened af & hard to move. This may be a sign of sexual yang recirculation happening, but possibly not in the right way. Any thoughts on what just happened there?
