My wife and I had wondered if you buttfucked once in a while, and see that you do!!!  Due to some aging issues, my wife can't anymore, but it's always nice to see those who can.  On the way to Burning Man the last few years, I stopped at different whorehouses to see about doing it, but of course it's quite expensive.  Thus it's nice to have wives and girlfriends who are amenable to it.
