As hot as it sounds, joining the famed-and infamous-Mile High Club these days is a risky venture. Sky marshals and heightened security have rendered this virtually impossible for most couples. Unless you can charter a jet, you may have to settle for hot places to have sex that are on solid ground. That being said, don't overlook the appeal of getting intimate on a cruise or any type of boat. The sound and motion of the water can do a lot to get your senses piqued.

Likewise, you're never too old for a skinny dip. Find a private lake, pool or secluded pond, ditch your clothes and have fun together.

The key to having sex outside of the bedroom is to be creative and have a sense of adventure. And remember that sexual intimacy isn't limited to intercourse. Anything you do that brings you and your partner closer together while outside of the bedroom is sure to help generate heat between the sheets.
