It is puzzling to me why the international default is to ban anything which causes people to feel horny, or which helps to release those feelings. Horny is a taboo feeling in most, if not all, mainstream contexts.

It's a mostly USA policy.

It exists in other countries too, but is far less strong.

I don’t believe this is true. The government and businesses of India and China are both notoriously sexually conservative. That’s a majority of humanity right there.
