First, people who abstain until marriage are generally less attractive.
They have to stay married because they don't have other options.
I'm not citing any empirical data. I'm just using my knowledge of the world and deductive reasoning.
Think about this: People have conscious explanations for their behavior. I don't steal because it's wrong and the Bible says so, for example. Easy to say when there are external reasons not to steal like potential punishment or not knowing how to pick a lock. But, what if that person had tons of easy opportunities every day to steal without any chance of getting caught. You better believe they're more likely to steal.
The same goes for sex. Some people have tons of opportunities to have sex with someone they find attractive. Take a high SES status, attractive white man living in Manhattan as an example. They have millions of options. I bet you that they aren't waiting until marriage. In contrast, take a poor, ugly, Mexican-American man from Yuma, Arizona. Not much of a singles scene there and most of the single American women aren't looking for a poor, ugly Mexican dude. Potentially, he's going to abstain from sex by default.
Then, imagine that both men are married. Is the guy who found the one woman in Yuma willing to settle for him going to get divorced? Who has more options to cheat? Who has the potential to trade up to a more compatible wife?
