To us humans the sex lives of many animals seem weird. In fact, by comparison with all the other animals, we are the ones with the weird sex lives. How did that come to be?Just count our bizarre ways. We are the only social species to insist on carrying out sex privately. Stranger yet, we have sex at any time, even when the female can’t be fertilized (for example, because she is already pregnant, post-menopausal, or between fertile cycles). A human female doesn’t know her precise time of fertility and certainly doesn’t advertise it to human males by the striking color changes, smells, and sounds used by other female mammals.
