Do Animals have Sex for Pleasure?

Not all animals have sex for pleasure. But there are a few species of animals like humans, Bonobo monkeys and dolphins that have been known to mate for pleasure, not just to make offspring. However most animals mate out of the primal need to produce offspring and increase the genetic pool before they die. Females are primarily the ones that encourage mating and rutting to occur because they become receptive to males during a particular time of year or during a particular time period. Males feel the need to breed as many females as possible to spread his genetics as much as possible.
