Good. Because getting married so that you can have sex is a bloody stupid reason to get married, which is what you seem to be implying.
I'm not implying, you're infering. Sex is only one component of marriage, having a partner in life, raising a family, etc. are others, but channeling one's sex drive into a relationship where it can have more meaning than whacking off used to be a much larger factor than it is today, and for decent men who didn't want to just use women as masturbatory recepticals, marriage was the only societally acceptable outlet. Now that women agree to be objectified, the incentive to marry is diminished.
