Good thread Scandolous.
I'm rather fond of anal sex myself. I think it's something only to be done occasionally, but it is a nice treat when my partner and I do it.
And, I thought I'd offer another perspective to this thread. I love taking it up the ass. Now for the record, I am straight, and when I say "it" I mean a toy being weilded by my Domme. It stimulates my prostate, feels damn good, and it's a good and fun way for me to submit to her. Again, I don't do this often, I don't want to mess anything up down there, and I am still pretty inexperienced, so it takes a little bit of coaxing to get started. But, once it gets going, I lose the ability to talk, and make intelligent thought processes.
I'm a bit nervous admitting this, since it has quite a stigma attached to it, but hey, this is one of the most open minded places I know.
