Of course, we all know that while men and women are both capable of cheating, it’s often the guys who have the biggest problem keeping their belts firmly buckled. And we all know that no matter who it’s with, why it’s done, or where the after-hours canoodling takes place, cheating is – most of the time – the ultimate relationship death sentence. But instead of dwelling on what happens after the cheating takes place, one of the ways to perhaps prevent infidelity is by knowing a little bit about why men stray.

Every time a celebrity couple is touched by infidelity – Pink’s hubby tries a different shade, or Ryan Phillippe spoons someone other than Reese – it’s like the rumble of distant thunder over our own relationships. Everywhere you look, you see potential targets for your partner’s straying eyes, hands and, heaven forbid, other body parts. There’s that co-worker, and the ex, and the spinning instructor with to-die-for quads (and glutes). Of course, most of us start relationships with complete trust in our partners – pumped on endorphins and often believing they have about as much chance of straying as Rosie has of buying a condo in Trump Tower.
