Harry was right!  Sally, not so much.  Science has confirmed that there is almost always an attraction between male and female friends-- and the most common result is dissatisfaction with current romantic partners.

The lead researcher of a study believes that platonic relationships are a relatively new concept in the history of humanity, so men are still controlled by their mating instincts.

The research results from the University of Wisconsin-Eau Claire showed that men more frequently admitted attraction to their female friends while also overestimating their friend's romantic feelings toward them.

In your experience, can men and women co-exist without attraction getting in the way?
