But even when they do want intimacy, they often don't know how to have it because of too many decades of hooking up (which isn't just about casual sex, but also about not even treating the other person with basic kindness or respect in many cases). I am just old enough that I remember dating pre-hookup culture. The sexual revolution started in the 60s and hook-up culture only really came into its current iteration in the early 90s. Sure, there were still one night stands and guys who weren't looking for relationships before that, but it didn't have this soulless consumerism aspect to it that it does now. Tinder is only 10 years old, so this idea of swipe and screw and then move on to the next one isn't exactly a long-standing dating dynamic.

The examples the author gave were about guys who were willing to woo her, to be in a relationship for months - but once they slept together they bailed. They were afraid of the actual vulnerability and intimacy of having sex with someone you like - at least that's what it looks like to me.
