There's something that's been bothering me for a while. I've always been very heterosexual, titties are great woot and all, but whenever I have any sort of sexual fantasy I always put myself in the woman's place. I've never really been aroused by the thought of sticking my dick anywhere, but the idea of being a woman with holes I don't even have getting brutally penetrated turns me on like nothing else. Tentacles are my favourite, but sometimes I'll fantasise about getting fucked by a man/several men, even though I have no attraction to men IRL. Obviously this is /d/, so I'm sure everyone else is just as fucked up as me, but is this particularly unusual? What sort of weird mental issues do I have?

TL;DR: Straight guy, has sexual fantasies about being a woman getting tentacle/regular raped. Comments?
