Sorry, that's rather artificial to me. It's flesh touching flesh. There is nothing more emotional about a mouth on a mouth than a cock in the ass. It's a physical act. People just like to draw their "lines" because it allows them to do virtually everything but still be who they want to project. If you want to be a virgin, give blowjobs, but don't have intercourse. If you want to be straight, be the top but not the bottom. And if you want to really be straight, fuck an ass, suck a cock but whatever you do, don't kiss--cause kissing is love. It's that type of delusional thinking that got George Bush elected to the office of the President not once but twice.
