Regnerus is a sociologist who defines cheap sex as sex that doesn’t require a lot of work [for men]. Porn, online dating, and the Pill are a few of the cultural markers that have cheapened sex. As a result, people are having more non-marital sex, but they aren’t any more fulfilled.
A big factor in all of this is that women are having sex with men they barely like fast as hell, which is fine in theory, but they’re also hoping that ~one day~ they’ll meet someone to really be with. But that “just sex” with those men is directly contributing to the climate of cheap sex because men will do what it takes to have sex and not much more. That might also explain why men today are less inclined to have their shit together or to excel in school or at a job–because they still get sex even if they are useless.
So he doesn’t respect your sexual freedom, he’s just happy it’s so cheap.
