As a demisexual, this idea is so alien to me. I have a high libido and I like to orgasm - a lot - but I don't see the appeal in sleeping with strangers when I could make myself get off, reliably and safely. And save actual sex for intimacy. I don't want a complete stranger entering my body. No thanks.
Not shaming people who like this. But I don't understand the appeal. For men either.
