If you've ever played Two Truths and a Lie, you know how it goes: A stranger whom you've just met offers up three personal facts about himself, with a catch—one is completely bogus. We're putting a spin on the classic icebreaker to find out how well you can tell health fact from fiction. Check out each trio of "truths" below and see if you can spot the lie:
A. Oral sex can cause cancer.
B. You can't catch herpes from sitting on a public toilet seat.
C. Using two condoms during sex is better than using one.
THE TRUTHS: (A) Oral cancer has been linked to the human papillomavirus, which can be spread through oral sex. (B) It's virtually impossible; the viruses that cause herpes can't survive outside the body for very long.
THE LIE: (C) "Double-wrapping" is counter-intuitive, says J. Dennis Fortenberry, M.D., of the American Sexual Health Association. Friction from using two condoms can increase the risk of breakage.
