well they can hit it from the back, it doesnt have to be anal, the vagina is very close to the anus, as a matter of fact I love it from the back too
Sounds nice
And yeah, I don't think it's a big deal, and may be really painfull if you tair tissue. Bet she wouldn't want to see you ever again if you did that and especially if you insisted (what I'm never planing to do). And you might get somekind of infection if you don't use a condome and like Spaz already said, I don't think it smells nice...
Anyway, glad that's out of my head. And I lost the problem that I thought about it every minute to. Now I'm the whole time thinking how I'm gonna get all the cash to buy all kinds of hardware
