Question

Besides humans, what other species has s*x for pleasure?

Answer 1

Besides humans? Your parents.

Answer 2

I know that some other primates have s*x for pleasure(at least it could be considered so, although it may be as a social interaction within a group rather than actual pleasure). Other mammals may do the same, and it seems that brain size has something to do with it. A good example would be the Bonobo, which has a lot of s*x, and not necessarily in a conventional way. Worth looking up.

Answer 3

dolphins also have s*x for pleasure.

Answer 4

s*x for pleasure is defined as s*x when reproduction isn't possible-when the female isn't in heat.  As far as I know, the only species this has been observed in are dolphins and bonobos, a primate closely related to chimps.
