Agree with KT and HHH. I don't see holding out for marriage as weird or abnormal - on the other hand I don't see it as superior, either. It just is. Though I will admit that waiting avoids the risk of unwanted pregnancy.

If I was dating and the lady told me she was saving herself for marriage, I would respect her choice and not deride her for it, but I would also end the dating relationship in an honest and respectful manner.
