I was in a hotel in Louisiana and a couple in the suite next to me had sex all night long. The bed squeaked, the head board banged the wall,,,, she was a screamer. I didn't sleep a wink all night and my ear was rubber raw from the pressing it against the wall.
Same here, I LOVE watching and listening to other people. I always try to pay it forward by getting my girlfriend to be as loud as possible when we stay in hotels.
