“You can keep cool and create different skin sensations by putting the fan in strategic positions,” says Lou Paget, a sex educator and author of The Great Lover Playbook: 365 Sexual Tips and Techniques to Keep the Fires Burning All Year Long. “Say you've been in the pool or shower and still have a little moisture on your skin. Air conditioning might be too much. But a fan that moves at varying temperatures across your bodies can do a range of cool things to keep you ‘hot.’” Paget suggests positioning a fan to oscillate over your naked bodies as you lay in bed with your eyes closed -- it'll be a pleasant surprise every time the cold air hits your body. Better yet? Preemptively warm parts of the body with your mouth before the fan gets there.
