Which other Primates besides Humans have face to face sex?

Bonobos copulate face-to-face, looking deeply into each other’s eyes.

This occurs about a third of the time during sexual encounters.

Humans once thought that they were unique in engaging in this especially intimate activity.

In fact, Western scientists once believed that face-to-face sex was not even a natural position for humans but was a more advanced cultural innovation that had to be taught to primitive peoples, hence the term missionary position.

Those clueless Western scientists were wrong on both counts.
