Animals that pursue s*x for pleasure?

Question

I am wondering about the different animals that have s*x for pleasure. I heard dolphins, monkeys, pigs, goats. but I'm not sure

Answer 1

Besides Humans, bonobos and dolphins are the only ones I can think of. (Usually as a social tool to strengthen and maintain bonds)

Answer 2

Aside from humans, the only animals known to mate purely for pleasure, rather than for procreation, are bonobos, chimps and dolphins. Bonobos regularly mate with all members of their group, regardless of the gender or age of their partner - they use s*x as a form of social bonding.
