Before I started on MFC, if someone had told me about the food crushing fetish, and that there are videos of women crushing food, and men jerking off to them, I probably would have said "Wow... that's not even remotely sexual. That's pretty damn weird." But I don't think anyone can expect anything else from a 20 year old with a non-sex-industry life.
Nowadays I hear of a fetish and I go "cool, so apparently there's a balloon fetish, too. You never stop learning lol", and then I go on with my day without thinking about it again, in most cases.
It's very rare for me to get guys with specific fetishes in my room (I don't know why! :|) but I've heard about lots of fetishes through this forum for example, and my view on them has definitely changed for the better that way since I started camming. Nothing that isn't illegal or has to do with objectively disgusting things really weirds me out anymore.
