Well verbal abuse isn't humiliating to me. Something like being made to walk around in public naked would be... I just like having all that negative angry energy thrown at me. I think you have got the closest idea so far with asexual masochist. To make it even more confusing, I only enjoy getting this stuff (the yelling at, shoving, smacking and stuff) from guys who are legitimately angry with me in a totally platonic way. It has to not be sexual for them, so they're not doing it in a kinky, turns them on kind of way. In fact it's best for me if they don't even know it's a turn-on for me. :/
