Hi, this may help many:
For many years, I thought that ejaculation-free sex and ejaculation-free masturbation were impossible for me. Maybe that's what you think of yourself also.
Later, I developed an ejaculation technique of masturbation that reduces POIS.
Later, I developed a technique of ejaculation-free sex and ejaculation-free masturbation.
Later, I developed how I can live a comfortable life without any sex and masturbation. (I only have sex after weeks, months, so that my partner is not neglected. I only masturbate after months when I feel inevitable (when something went wrong).
I plan to write about these things in the future at this forum.
In this book you can read about similar things:
The Multiple Orgasmic Man: Sexual Secrets Every Man Should Know
(..."Learn to separate orgasm and ejaculation! Enjoy increased vitality and longevity!"...)
This is hopeful for a POIS-free life!
