Dr.Tatiana's Sex Advice to All Creation

Evolutionary biologist Olivia Judson presents "letters" from sexually frustrated animals, birds, and insects who ask "Dr. Tatiana" to explain some sexual oddity. You'll learn why one stick-insect copulation lasts for 10 weeks (to prevent other males from gaining access to the fertile female) and why the black-winged damselfly's penis has bristles (to scrape out his rival's sperm). You'll learn that male and female orangutans masturbate with sex toys fashioned from leaves and twigs, that slugs are hermaphrodites with penises on their heads, and that females in more than 80 species eat their lovers before, during, or after sex. You'll also ponder human sexuality when you learn that "monogamy is one of the most deviant behaviors in biology" and "natural selection, it seems, often smiles on strumpets."
