What drives people to collect their own semen?
Is it a sexual fetish? Do they think they’ll need it later? How long does the actual sperm last? Do they intend to impregnate a woman with it later? Is this some sort of psychological abnormality and they’re insane?
Note, I’m talking more about people who collect their own semen than sperm banks and those sorts of institutions.
While I note the taboo with this act, I suppose they have every right to keep their semen for themselves.
