Three times Quote by Christopher Ryan
““In gorillas’ winner-take-all approach to mating, males compete to see who gets all the booty, as it were. So, although an adult silverback gorilla weighs in at around four hundred pounds, his penis is just over an inch long, at full mast, and his testicles are the size of kidney beans, though you’d have trouble finding them, as they’re safely tucked up inside his body. A one-hundred-pound bonobo has a penis three times as long as the gorilla’s and testicles the size of chicken eggs. The extra-large, AAA type (see chart in Chapter Fifteen). In bonobos, since everybody gets some sugar, the competition takes place on the level of the sperm cell, not at the level of the individual male.””

![“[Man] has imagined a heaven, and has left entirely out of it the supremest of all his delights, the one ecstasy that stands first and foremost in the heart of every individual of his race…sexual intercourse! It is as if a lost and perishing person in a roasting desert should be told by a rescuer…” quote by Christopher Ryan](https://sms4smile.com/quotes/img-quotes/939/christopher-ryan-4309_joy_man-has-imagined-a-heaven-and-has-left-e_187069.jpg)
