Ask them about bonobos:
Bonobo - Wikipedia, the free encyclopedia
"Sexual intercourse plays a major role in Bonobo society, being used as a greeting, a means of conflict resolution and post-conflict reconciliation, and as favors traded by the females in exchange for food. Bonobos are the only non-human apes to have been observed engaging in all of the following sexual activities: face-to-face genital sex (most frequently female-female, then male-female and male-male), tongue kissing, and oral sex.[15] In scientific literature, the female-female sex is often referred to as GG rubbing or genital-genital rubbing, while male-male sex is sometimes referred to as penis fencing
"Bonobo females also engage in female-female genital sex (tribadism) to socially bond with each other, thus forming a female nucleus of Bonobo society. The bonding between females allows them to dominate Bonobo society - although male Bonobos are individually stronger, they cannot stand alone against a united group of females. Adolescent females often leave their native community to join another community. Sexual bonding with other females establishes the new females as members of the group."
