[Cthulhu_]

It's one tactic to try and avoid them 'accidentally' having sex at a young age (and getting pregnant and everything). I can kind of see everything, I mean on the one side sex ed is important, but if they can avoid attempting it for a few years until they're more well-rounded individuals it'll be a double bonus.

Mind you, I've very much been a late bloomer so my perspective is probably not representative.
