What doesn’t work about this is that people desire sex with people they want, not with who might be good for them. For instance, during the women’s lib movement of the 60s and 70s, there were some radicals who theorized men were The Enemy, and that women should only be with other women. Well, that never took off (beyond some experimentation) because people can’t just switch their sexual desires at will. And even if we could go through with some acts once in a while (as in the cases of closeted gay men who marry women and even have children) it doesn’t lead to a fulfilled life.
