Dr. Trina's One Sheet

Monogamy: the life-long sexual exclusivity, with the expectation of continued, enjoyable sexual intimacy through middle- and old-age-is a relatively recent, very radical social experiment. Oddly enough, it's still the gold standard of sexual relating even though it's actually pretty unusual-and no one seems to have a dependable formula for how to create and enjoy it.
