Virginity is very, very beautiful, and like Manison said, I think it would be a fair game to expect a virgin partner if one is virgin, too. Marriage is more about love, trust, and understanding; so they play more important roles. If one is ready to accept the partner who is not virgin, but who has much love to him/her, then s/he (the one who is ready to accept the non-virgin partner) just have a bigger heart.
