A sex guide for all living things and a hilarious natural history in the form of letters to and answers from the preeminent sexpert in all creation.

Dr. Tatiana's Sex Advice to All Creation is a unique guidebook to sex. It reveals, for example, when necrophilia is acceptable and who should commit bestiality with whom. It discloses the best time to have a sex change, how to have a virgin birth, and when to eat your lover. It also advises on more mundane matters -- such as male pregnancy and the joys of a detachable penis.

Entertaining, funny, and marvelously illuminating, the book comprises letters from all creatures worried about their bizarre sex lives to the wise Dr. Tatiana, the only sex columnist in creation with a prodigious knowledge of evolutionary biology. Fusing natural history with advice to the lovelorn, blending wit and rigor, she is able to reassure her anxious correspondents that although the acts they describe might sound appalling and unnatural, they are all perfectly normal -- so long as you are not a human. In the process, she explains the science behind it all, from Darwin's theory of sexual selection to why sexual reproduction exists at all. Applying human standards to the natural world, in the end she reveals the wonders of both.
