In a car, in the bed of a truck, on a roof, in my back yard, on my front lawn once late at night, along the river trails a bunch of times including threesomes, store dressing room, guy shower, gym sauna, hotel pool, hotel hottub, on a quad in a field, on a dock, couple public bathrooms, behind some closed businesses, park, middle of a road and middle of an intersection not kidding, at parties, in a bar, on a cablecar in Frisco, by the train tracks a bunch of times, probably a dozen model homes in almost any room you could think of, on a boat, on a raft, neighbors yard while they were gone, my work office, other folks work, on a freeway overcrossing at night, bank parkinglot, sheds for sale at big stores, couple fast food places in the bathroom, about any place else you could probably name including several church parking lots, and in a library.
In my bed, in my mom's bed when I was younger, just about every room in the house. Behind a park in the woods by a river, movie theater, in the back seat of a mutual friend's car while he was driving us somewhere, in the bathroom of a notorious gay bar in the area. I'm not proud of all of these - but they were mostly fun.
Public beach, woods, church convention (my first sexual encounter with a woman), in a car, at the fair, at school (high school), and most recently, in a jacuzzi at a spa (on our honeymoon).
Ironically, I'm not an exhibitionist at all.
In high school my boyfriend and I used to have sex on the stairs between floors right smack dab in the middle of school. I'd wear a skirt and sttraddle him. His pants were so baggy no one who cared evervknew
In the back of a Rec center at night when no one was around we did it by the pool on all the fun pool things like life jackets and floaties. Also in a cemetery, river (swimming spot), Drive-ins, Library, and my favorite; at his college in one of the classrooms (it was extra sexy cause it was mid-day )
My husband and I had sex in the back of a 1940s Ford firetruck once. It was a bit uncomfortable but firetruck was on his sex bucket list and we were stuck in a situation where we couldn't get to a room.
