There are plenty who want sex b4 marriage, but not so many who give in to those urges before marriage. This is because of the double standard when it comes to men and women. A woman will be told it's ok by a man until he's tired of her. Then he'll brag and her name will be dragged through the mud by others(even if the guy says only good things about her morals and such), due to this, when it's time for marriage, no man would want her due to ego; and his family wouldn't want her due to respect. Because for a woman, how she is as a person is tied to sex, and if she satisfies desires and people know, then she's considered unfit to marry a good man. Plus, when a girl has sex, she wants to share, it's a need for both sexes...but she's not allowed to..but probably needs to more so than a guy because girls usually tie emotions to sex, and this makes them vunerable, and they need to get it out. But this type of openness only gets her in trouble in the eyes of everyone. So she is advised just to keep her legs closed 'til marriage...or face the consequences...and relizes that it's easier that way.
