 What is the writer's opinion of the instructional videos advertised in the New York Times Book Review?
More Bang for the Buck A friend of mine offers a theory about why Bill Clinton's poll numbers stayed so high throughout the Lewinsky scandal: The news made it possible for serious-minded people to spend lots of time--at the office and over lunch--talking about semen stains, vaginal insertions, and blow jobs. That's probably because they're not getting all that much themselves.

Unless it works. But then I got to thinking: Under battlefield conditions it doesn't get out anyway. And while I should have been paying more attention to other things, this led to thinking about the old joke with the punch line "... and right ball go POW." Overall rating, on a scale of 1 to 10: 2 toes curled. A woman I know says women's magazines are the best places in America to find sex tips. She's right--go ahead, just try to find a sewing pattern in Redbook . You're much more likely to land on "Try phone sex, dirty notes, porn videos, fantasy games and sex in new places. ...
