I heard the opposite. I saved myself for marriage of course, but I have friends that knew many women in the Biblical sense. Seems some of the "loosest" women could be quite boring, while the "shy, good girls" could be quite adventurous. Not sure that it really matters, sex is for procreation and is a Holy gift from God that should be restricted to the confines of blessed matrimony.
I saved myself for marriage...three times (so far)
