Yeah there really are such people.

The whole mass of humanity is mostly doing whatever feels kind of normal most of the time and not thinking about it.

Countering the momentum of “holy shit I really want to be fucking right now I am so hot for this” takes a LOT of work.

If you can make “I changed my mind and I don’t want to get fucked after all” a thing then you need to seed that idea in advance firmly in the mind of insecure young people who never had any deep thought about sex at all before.
