A study of macaque monkeys in Indonesia found that males "paid" for sex through favors to females. The payment was offered up front: a grooming session for the female. When groomed, female sexual activity more than doubled. However, when the number of females increased, the males' willingness to trade for sex went down. In summary, the oldest profession in the world is not just for humans.

Males get it on this, too: they perform their own variation of this act wherein they, um, "swordfight." Yeah, they rub their penises together while hanging from a branch.
