I am versatile though, just not when it comes to oral.
I find this incredibly interesting. Only because it's the exact opposite of me. To be honest, I'm not even that into the whole anal thing to begin with. It's probably why I'd never have any sort of group sex either. Which brings me to my next point.
There's something really worrying, to me, about group sex. It's probably the anonymity but I haven't accepted any of the invites for it. I guess it's probably the increased chance for stds and the decreased assurance of personal safety.
