Hey dude, if she wants it in the ass then let her have it. I personally dont like anal but I've had one ex-gf who loved it... So whatever, you do what ya gotta do to keep her happy.

I would say though vaginal is much much better... Though maybe she is kinda not wanting to lose her virginity just yet so maybe that is why she wants it up her ass.

I say just do whatever she feels comfortable with. Either way you're going get a 'piece of ass'
