If you've ever DP'd a chick, which means you fuckered one hole while another dude fudded the other, I think it's a 50% homosexual act... lemme explain.
Now when I fuck a girl doggie and pull my signature move, the finger in the poop chute, I can feel my cock sliding in and out of her pahgynah from the finger in the ass, and vice versa.
SO, logically replace the finger with your buddies cock and you are basically rubbing eachothers cocks together sheilded by a thin female layer of skin. That's pretty fucking gay. Now add into it your balls are prolly gonna touch, dicks might poke, and if one of ya pulls out and sprays, it's man on man cumshot city.
That's all I have to say about this particular topic, any thoughts?
