Why Is the Penis Shaped Like That: And Other Reflections on Being Human

Bering is a little jokey jokey (which I remember from Perv) but he’s also a smart scientist type who likes to talk about evolutionary biology and reasons why things might be the way they are. In this book he tackles things like the shape of the penis, the details of female ejaculation, what evolutionary purpose gay people might have and a host of other things. It’s a good book, it’s well researched and it’s funny. Also I read it on my Kindle so I didn’t have to worry about weird looks from people on the bus or subway.
