Marriage Sex: Getting Busy Is Key To A Successful Relationship, Expert Says (VIDEO)

The Key To A Successful Marriage Is...

What makes a good marriage last forever? A healthy sex life, according to Andrea Syrtash, author of "Cheat On Your Husband (With Your Husband)."

Syrtash stopped by HuffPost Live Tuesday to discuss the importance of of sex in marriage. "Sex is the one thing you can't get outside of marriage -- unless you're looking to cheat, which is another topic," she said. "If your partner doesn't like museums, you can recruit someone else to go with you to do that. But sex is one of those things that binds us together."

The good news is that married people tend to have more sex than single people, and, according to sexual health expert Dr. Laura Berman, "they also have more varied sex." High five, married people!
