Bonobos

While some creatures ‘mate for life’ the bonobo mates throughout life, all the time, with anyone it can as often as it can. These sexually rapacious creatures don’t exclusively have sex to reproduce, like ourselves, they consider sex as a social activity. However, unlike us, a male bonobo has no issue having sex with a female that still has a baby clinging to it and she doesn’t seem all that bothered by this either.

The concept of monogamy is also foreign to bonobos and they will literally have sex with anyone and everyone, which also means that heterosexuality is not something they strictly adhere to. Sex is used to establish social rank and is even used as sort of currency.
