“Bonobo sex comes in all forms: female to female, female to male, and male to male. I put the lady sex at the beginning of this list because bonobos also live in a matriarchy. Researchers have noted female Bonobos practicing tribbing (clitoris to clitoris rubbing) to help smooth out problems. Lead females will work out their tension together for around 20 seconds. In that time there is a measurable heart rate increase, facial flushing, shrieking, and clitoris engorgement. All the usual signs of pleasure and orgasm. They also participate in kissing with tongue, and oral sex. Males and females will of course procreate, and they do it more or less with everyone. They also practice some amount of face to face mating; looking at each other during the act.”

“Once the female has been found, the male will swim up to her and bite down on some part of her body. From this point forward he will never let go for the rest of his life. He has now transitioned into a parasite, taking in nutrients directly through the female and her blood stream. His mouth, eyes, and face will fuse into the female's skin and he will essentially become a tumor on her side. His only function from this point onwards is to be a pair of gonads, to provide sperm on demand when the lady Angler Fish is ready to fertilize her eggs.”
