In today's western societies, virginity is not a greatly-prized virtue. The sluts get all the attention, while virgins are actively shamed.
Even after marriage, when I am no longer a virgin, women tell me that I should have slept around before marriage. How can I know I'm having good sex if I haven't had it with numerous other men?! The fact that I'm enjoying it and having frequent orgasms isn't enough - according to them, I need to have experience with other men to really be able to tell if I'm having a good time with my husband in bed. As ridiculous as it may sound, this is the message being drummed into women and girls: if you don't ride the cock carousel in your teens and twenties, you won't be able to truly tell if you are having sexual pleasure for the rest of your life.
Slutty women are unlikely to start suddenly praising virginity, as it makes them look worse by comparison. With the vast numbers of sluts in the US, this means most women are not going to come out in favor of girls saving themselves for marriage, or at least engagement. Therefore, if men would prefer to marry virgins, they will need to be the ones to reward virginity.
When was the last time you heard a man bragging that his wife was a virgin the first time he had her? Never, I'll bet. Yet, men boast all the time about the whores they've been with. It's time for men who marry virgins to brag as loudly as the ones who bang sluts. There should be no doubt in anyone's mind, least of all his wife's, that he is proud to have been the one to deflower her, as well as the only man to have had her since.
It's not a bad idea for the rewards to be tangible as well. I once met a Muslim woman who told me that in her culture a man is very pleased if his wife is a virgin on their wedding night. He will usually give her expensive jewelry to show his approval and appreciation. Having a piece of jewelry to wear as a reminder of this is both an encouragement to other girls and women not to give their virginity away to men who don't commit to them and also an incentive for the wife to remain faithful to her husband. After all, if he valued her virginity so highly, he will likely value her marital faithfulness as well.
Or we could just go back to displaying the bloody sheet as proof of the bride's innocence on the wedding night. Now there’s a way to make feminists die of sudden heart failure.
