You catch her eye across the aisle. Not once, but again and again. You know that look. Can it be? Is this girl interested? You give her that knowing look back and then “the nod.” Getting up from your seat, you hear the click of her belt releasing. You meet in the tiny space, slipping in together somehow unnoticed – you hope.

With little room to navigate, your bodies come together quickly and with purpose. Within moments, you both reach fever pitch and collapse against the thin divide between the two of you and the rest of the world. No names exchanged, you return to your seats. You just got your membership. Welcome to the Mile High Club.

Exciting, hmmm? At least in theory. I’ve never done it myself. The quarters are a little too tight (and germy) for my taste. Still, the idea of it… and whether it’s with a sexy stranger or your own partner in crime, the thought of coupling in public is hot. Will you get caught? Can anyone hear you? What will happen if you’re exposed?

If not the bathroom, I believe you can still become a card-carrying member with a little under-the-blanket action. The point is still the same – doing what you want to be doing where you should not be doing it.

Of course, airplanes aren’t the only way to fly, as it were. Sure, you can’t get your mile-high membership if you’re grounded. But you can certainly feed the desire for thrilling sex. It’s all about going as close to the edge as you dare – whatever that means for you…

Restaurants are prime locales, especially when the tables have long tablecloths. Ask your lover to skip the undergarments and opt for a short skirt or seek out a restaurant with a single occupancy restroom with room for two nonetheless. The back of dark clubs and even alleyways are favorite haunts of the truly adventurous. Not to mention the car, the park, your office...

Now, if you’re up for the thrill but not quite ready to go so far down the line, there are still plenty of thrill-seeking options. Contrary to popular belief, the bedroom is not the only place to get down.

How about the kitchen? You never know who might be able to see into that sun-filled window.

Or maybe the living room floor? Is your mother-in-law scheduled to arrive today or tomorrow? And did she ever return that key?

How about that hammock in the yard? Especially if your neighbors are gardening next door. Oooo. Or the flower beds? Talk about getting down and dirty!

The point is, the fear of getting caught -- combined with the thrill of being naughty by taking things out of the bedroom -- can really ramp up your sex life. No stranger required. (Although, if you want a real thrill… But that’s a whole other column).

Thrill-seeker sex requires only three elements:

1. Risk – Can anyone see you? Is there a chance of getting caught? If the answer to either of those questions is yes, you’re on the right track.

2. Surprise – If you or your partner had no idea this is where the day would take you, a great ride is definitely in the cards.

3. Unusual locale – Even if it’s a place where others may have treaded before, if it’s new to you and your partner, it’s game on.

You don’t have to go far from home to take your sex life to a new level. You just have to leave the expected behind. Take a risk. It’s amazing how much great sex has to do with location, location, location...
