ok, we've had several variations on this ... so, if you could have sex any where in the world, where would it be ? in the middle of the road, town square ... anywhere. I would have to say the observation window in the CN tower in Toronto ...
theatre, car, washroom, tent, field, forest, top of a building,library, kitchen table, airport and the mall
on train tracks, in the water (swimming pool, creek, river, ocean, etc), on a train, ANYWHERE REALLY!
in a body of water (shallow enough to stand in of course), with a waterfall, and beautiful lush woods and forestry around, and as a person stated above, in a tree during pouring down rain would be beautiful as hell too, and it could be day and/or night.
ha...on a small floating dock in the ocean on a sunny day...not out of sight of a very populated beach
in the middle of a field on a blanket under a thousand stars on a warm summer night. In a tree (almost been done but too many other poeple climbing the tree ) In a tree house on a beach (not a stoney one )
In the desert in the old southwest outside under the stars like the Eagles song.."i wanna sleep with you in the desert tonight. with a billion stars all around*
in the mud at a festival, during a really good show on the beach (desterted beach that is!) in hawaii on a warm rainy night anywhere else in a summer rainstorm would be quite nice too in the ocean
