Why Do Men Cheat? (VIDEO)

What leads some men to cheat?

In the YourTango "Ask an Expert" video above, relationship coach LiYana Silver reveals what she believes is a common cause of infidelity.

"We think it has to do with sex -- that men trade up for a younger, or thinner, or hotter, or blonder babe," she says. "Sex is important, it's on the list, it's just not at the top of the list."

The number one reason men cheat, according to Silver? "Lack of emotional appreciation."

Watch the video above for tips on how to demonstrate emotional appreciation and tell us what you think in the comments.
