This is a refreshing and incisive scientific view of a subject of primary interest to humankind,(i.e., sex, in case you hadn't worked it out), lightly written with a dry sense of humour. Sexual issues properly concern politics and society, and Dr M. completely demolishes various myths that permeate popular debate.
You can tell a book by the quality of its references, and as you would expect from a doctor in epidemiology, the argument is grounded in robust evidence.
She convincingly destroys, for example, the myths that rapes rise in districts with strip clubs, and that there is a huge "trafficking sex trade." The myths are not only wrong but the mis-information positively damages effective efforts to reduce rape and trafficking.
So it is good reading and if you are interested in social issues, essential, to consider evidence before arguing for policy.
