The Dilemma: How to get over a man-summer gone bad? Ban males next time out.

The Bet: No sex this summer vacation. So who will not hold out the longest?

First there was Bianca -- Bianca St. James is desperately pretending her billionaire playboy client isn't fiendishly hot. Self-control... not a chance!

Then Madison -- Safely away from temptation, Madison Garrett's confident she'll win the wager... until she sees her travel companion. Will all bets -- and clothes -- be off?

And finally Emma -- Emma Jacobs was set up. Now she's alone in the wilderness with her achingly hot former high school sweetie... surely no one will notice if she's a little bad, will they?

May the best woman win!
