Time to get rid of your most attractive friends.  According to this new survey.. more than two-thirds of men say they've fantasized about their wife or girlfriend's friends in the past.. and plenty of them still do it now. 

45% have done it in the past but try not to anymore.

25% did it in the past and plan to keep on doing it in the future.

0% chance I've ever done it (just in case my Ryann is reading this)
