I do take offense to those who say "that Sister probably masturbated herself" or "everyone masturbates". I've never masturbated (or had sex). I think it's disgusting - it's just not for me. It's everyone's own business - again, as long as they wash their hands afterwards (and, preferably, don't talk about it too often where I can hear but I understand that's a bit too much to ask). But saying everyone does it, or that that person probably did it also.. that doesn't HAVE to be the case.
