Is there any change that a girl looses her virginity by having sex ONLY in her ass?

actually yes sometimes

If I buy a used car and ask the dealer if it's ever been wrecked and he says, "not in the front end," is that the answer I'm looking for?

If the purpose for preserving your virginity is to save yourself for that special person, does anybody think that he would feel any different learning you saved one orifice for him but gave another to someone else?

The premise of this question is based on a rationalization.

That is a really smart answer :D
