I dunno, sex is one of the most primal urges any animal has, maybe even more primal than hunger and thirst.
If you had to spend years not even being allowed to masturbate, I'm pretty sure that giving in wouldn't qualify you as "weak", it'd qualify you as "normal" (unless you go the kiddy fiddler route, in which case, fuck you.)
Unless you don't have a sex drive to begin with, in which case, good for you.
