Not sure why seeing a face in a man's ass is disturbing, but it is. While I pride myself in being an "I'll do anything once" kind of person, I have to admit that putting my face in someone's ass brings up certain health issues that I avoid. Like ebola.
As to damaging anthropomorphic toys... My first thought is that it's twisted. Upon reflection, I can see the fun in it. It's got to be cathartic on some level. There was an episode of Roseanne where they found Barbie parts in a box under DJ's bed. All I could think was that he was a serial killer in the making. But now I know it's just clean fun. LMAO!
