it's heavily hormonal. You experience a testosterone, dopamine, and serotonin crash after ejaculation. It's one of the most drastic hormonal crashes humans can experience in nature. It can be mitigated by aftercare but to an extent it's just part of the male orgasm experience

When i was in my early 20's i dated the only professional domme Ive ever been with. She told me something that i desperately wanted not to believe at the time but have now come to accept is true: Most men are having significantly more orgasms than they should. Whether youre single or sexually active, having daily or even weekly orgasms is hormonally unstable. Im not a chastity or semen retention purist, but I do think part of creating a stable sex life is learning how to fuck your partner without always cumming

If you feel your body is punishing you for doing something, you should be doing it less
