February reads-too racy for review!

I jotted down a few reads recommended on NPR during a Valentine's Day spot. I requested the books from the library and they came in in late February. One well researched book was extremely educational, another was awfully pornographic. I thought I shouldn't review them here. But, keep in mind that these books were reviewed on NPR, and they were available to take out at the library. And completely inappropriate for young adults. Certainly WAY TOO MUCH INFORMATION for kids.
Beware.
