Hotel pools and hot tubs many times. Lifeguard tower many times, I grew in Ft. Lauderdale and was at the beach almost everyday.
On a trampoline, pulled over on the side of a major highway, at a rest stop. In a military HumV. In my Commanding Officers office while on guard duty.
When I was stationed in NC and my wife and I were still engaged she cam up to visit me once and on the way to take her back to the airport w pulled off in a construction site and did it on the hood of my car. As we finish and started to get dressed we heard applause of in the distance. OOPS we thought we were alone.
