"Unprotected" by Dr. Anonymous. This new book by a campus physician was reviewed this week by the WSJ, but I cannot link to the review. Here is another review, however. What irony: in the university world, the hazards of over- and under-eating are carefully addressed, smoking is frowned upon, fatty diets and insufficient exercise are condemned. But the health consequences of unrestrained sex are ignored.
The WSJ review:
As the author observes, "surveys have found that sexually active girls were more than three times as likely to be depressed, and nearly three times as likely to have had a suicide attempt, than girls who were not sexually active."
