2 Facts about Bonobo

Make Love, Not War

Bonobos use sex for conflict resolution, greeting, and social bonding — engaging in sexual activity regardless of gender, age, or reproductive state.

Sex as a Social Tool

Bonobos have sex multiple times per day in various combinations — male-female, female-female, even adult-juvenile — using it to resolve conflicts, reduce tension, and strengthen bonds.
