WASHINGTON (CBS DC) — A new survey finds that couples who travel together have better sexual relationships than those who don’t.

Almost two-thirds of couples surveyed by the U.S. Travel Association found that a weekend vacation is more likely to spark romance in their relationship than a gift. Seventy two percent of the 1,100 American adults surveyed said that travelling inspires their romance.

More than three-quarters – 77 percent – of those who travel as couples reported that they have a good sex life. This is in comparison to 63 percent of couples who said they do not travel as a pair. And 28 percent of the couples say their sex life has actually improved after travelling with each other.

Of those couples, 40 percent said the improvement was a permanent one.

“When you’re away all of a sudden the e-mails don’t happen, neighbors don’t knock on the door, and the dog doesn’t have to be walked, and you get to spend more time together,” Roger Dow, president of the U.S. Travel Association, told USA Today.

People who often travel for business said that taking their spouse with them had a positive effect as well.

“People don’t realize that being a frequent flier and road warrior is a very lonely life,” Tamara Hall, a consultant in Bozeman, Mont., told USA Today. “When we travel together, it cuts the work and stress in half.”

Of couples who travel together, 84 percent made their relationships last at least five years. Of those who didn’t travel together, 76 percent stayed together longer than five years.

Sarah Rodgers, senior research analyst at Edge Research — which conducted the survey — says that couples who traveled with just each other, rather than being with friends or other couples, are more likely to feel closer and communicate better after a trip. Traveling allowed them to “talk and reconnect and also to share new experiences,” she told USA Today.

But University of Alabama at Birmingham clinical psychologist says that not all couples travel well together.

“Just traveling together in and of itself is not going to make you a better couple, but learning how to travel together successfully is,” he says. “Traveling together puts a couple in an extended period of being together more than their average interactions. That extended period can either enhance a relationship, or it can blow up in their faces.”
