A lot less erotic and a lot more funny than you might imagine from reading the title, Bonk by Mary Roach examines the outrageous methods humans have used to study sex. Some of her examples reach back into history, from the ancient Greeks to the 1920s. But many of the studies Roach cites are more recent, and these might inspire you in inquire how it is you could get into this line of work. What’s especially amazing is how mysterious such an important and instinctual act for humans still is. Bonk is a compelling and entertaining read.
