Article is from 2016 and doesn't provide any evidence about the rise of sex for pleasure.

Not worth your time.

The article also claims sex is fun without any corroborating data. Highly suspicious!

I think that science demands a double-blind trial to test whether sex is fun or whether it is just a placebo effect :)

Evidence is a hard word in paleontology. The article does discuss fossils which provide clues, which is as good as it gets for most of the field.
