File idea : orgasm block

[svargen1]

Person can masturbate as much as they like, right to the edge but they are unable to ejaculate for a given length of time(preferably the user could somehow chose their own time frame). Also preferably nothing involving permanent curses or the like. I may like the idea of not being able to cum fora certain length of time. Of course intercourse would still allow ejaculation.

Thanks for considering.
