Did you know? .....that the life of the bonobo, or "dwarf ", is consumed by sex. Sex is used as a social greeting, as conflict resolution, and post-conflict resolution. They are the only non-human animal known to engage in oral sex, tongue-kissing, and face-to-face genital sex. They don't discriminate based on sex or age and so female-famale, male-male, mother-adult son, etc., contact is all not uncommon. There are literally scientific terms used to describe social sexual contact such as "rump rubbing" and "penis fencing".
Just a fun fact for you all about bonobo!
