Masturbation Or Sex: Can You Tell The Difference (And Win A Sex Toy)?

Sure, you've been masturbating for most of your life ... but do you really know what masturbation looks like? As part of our monthlong celebration of masturbation, we're offering our readers a chance to show off their fapping smarts ... and win a pretty fabulous prize in the process.

Below are ten photos of different models' faces. Some of these women are masturbating, and some of them are having sex. Can you tell the difference? Get all of them right and you'll be entered in a random drawing to win a (brand new, we promise) Delight vibrator, guaranteed to make your National Masturbation Month a lot more fun.

How To Enter: Make a list from 1 to 10 and tell us your best guesses in a comment to this post. (Don't have a Fleshbot/Gawker Media commenter account? Get one--it's easy.) Next week, we'll choose a winner based on whoever has the most number of correct guesses--or will randomly choose from entries in the case of a tie. We'll let you know via your commenter profile page what you'll need to do to claim your prize.
