It's interesting that our two closest primate relatives are Bonobos and Chimpanzees. Bonobos are highly sexual and their sex habits match the full range of human sexual behaviors. Chimpanzees practice tribal warfare can be horrific murderers. Humans exceed both our relative species in both of these areas.
I think not. But matching a basic subset perhaps.
E.g. I don't think you'll find many bonobos jerking off to internet porn.
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.
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.
In any case bonobos would not write Kama Sutra even in 20,000 years. Your timescale and argument is way off.
