. . . because The History Channel is running “The History of Sex” again. And as I write, it’s sister channel, History International, is airing “Sex in War: Sex in Vietnam.”

A couple of times each year History Channel puts aside it’s overviews of the Peloponnesian War and rehashes of the Titanic’s sinking (all of which I like, by the way) and tries to sex things up a little bit for a ratings boost.

I guess it’s that time again.
