That's like saying humans have evolved radically different behavior compared to 200 years ago because back then they couldn't travel to another celestial body.

I would argue jerking off to Internet porn and jerking off to a fantasy are both exhibiting the same behavior, just like a polar explorer from the 19th century and a lunar explorer from the 20th century are exhibiting the same behavior.

Indeed the core of it is the capability for complex sexual fantasies, and human behaviour is not limited to simply just jerking off.

I'm not saying humans 200 years ago were incapable of such things.

What I'm saying is that bonobos don't read or write Kama Sutra.

Go back 20 000 years and modern humans didn’t write Kama Sutra either, because just like bonobos we lacked the technology and knowledge to write.
