Yeh, I read a interview years ago where Burt Lancaster commented on that hot love scene he and Deborah Kerr did on the beach. He said that there was no way he could do that for real, there was sand in places that sand should not be in.
As for the most sensual place to have sex? Well, I can tell you were it's not.
A few nights ago, Sarah and I had went out, ended up in our favorite outcall for the night. For some reason, as we were undressing each other, things got really hot, really quick, and we ended up on the floor. It seemed like a really good idea at the time, but at my age, screwing on the floor is not all it's cracked up to be.
