Signed, sealed, delivered, I'm yours...
I had to post this. If only all my textbooks were this interesting...
"Now consider other cultures... What about our rates of sexual contact? The Zande have sex two or three times a night, and then once again upon awakening. Chaga men have about ten orgasms a night, and Thonga men try to have sex with as many as three or four of their wives each night. But few beat the Marquesa: While it's not uncommon for a Marquesan man to have thirty or more orgasms a night, it is normal to have at least ten. Older married men are exempted: They have only about three or four a night. By contrast, the Yapese have sex only once a month or so. During this encounter, the man sits with his back against the side of the hut and his legs straight out. The woman straddles him, and he inserts his penis into her vagina a little bit, and then proceeds to stimulate her for several hours while she has dozens of orgasms."
