Why virginity is so good

Speaking to friend last night, we were drawn into a conversation on our perspectives on virginity and what I personally felt about the reason virginity should be treated as something that should be gifted to one's spouse.

My belief is simple and two-tiered:

1) God created sexuality as a beautiful, delightful and wholesome act. It is no doubt the most pleasurable physical act in all of humanity. And yet, when He decided to become a human, He chose to do so through the body of a virgin. Now if my own Creator, the Master of the universe and the Creator of sexuality Himself chose to be born through a virgin, (thereby implying the respect even He has for virgins), how much more respect should I as a human have for it
2) Virginity - being a gift of spouse to spouse - is entirely dependent on permission, or put more simply, two 'yes's. Whenever I think of giving one's virginity up, I remember Mary and the Annunciation. At that moment of the Yes of Salvation, even God in His power chose to ask the permission of Mary. And her saying Yes wasn't simply her giving permission to the Holy Spirit. Her saying Yes was her allowing God to say Yes to her as well. So, when a wife gives her virginity to her husband, she is mimicing Mary, while when a husband does so, he is mimicing the yes of the Holy Spirit.

Isn't is obvious, then, that virginity is a divine gift, not simply a human one? Then I must treat it so.
