Did I mention I love Mary Roach's writing, her puns and the overall ease with which she pursues her topics? Because I do.
Bonk is after Stiff the second book of her I read, and it is even more fun and light-hearted (probably due to the fun and light-hearted topic). Nevertheless it's interesting, well researched and has given me a lot of insight into what's going on in bedrooms all over.
The quote which struck me the hardest and will probably stick with me for a while was: "American manhood would not abide the sexually sophisticated (i.e., demanding) woman, and it fought back hard." That happened in the 1950s. Seems like some of them are still fighting today.
