It means OP is terrified of being compared to someone else. With a virgin, no problem : they've no idea how bad you are, really. Unless they have friends, of course.
I mean, there is the lovely notion that as a happy loving couple, you'll discover your way together. And really, I think that's a great romantic idea. In theory.
Unfortunately it seems to fall over if you couple it with the "do not talk about it ever" sex education.
So many unsatisfied women out there just living with the "well, that's my life now" attitude. It's tragic.
