I was wondering that too, learn something new everyday.
I'd like to think that I would wait to have any type of sex until i'm in a commited relationship, but since that seems unlikely to happen anytime soon since good boyfriends or boyfriends in general are so hard to find. However, when i find said boyfriend (hint hint Wally Szczerbiak thats your cue) I think I would be up for anything, I mean this is Wally were talking about here. Guess as long as were both okay with it and respect each other afterwards and during, and are comfortable nothing reasonable should be off limits as long as were safe.
