I totally agree that it is always fun to be a voyeur, but on the flip side, a few months ago, I was in a hotel room with a girl I was dating at the time. The desk in the room was positioned in front of the window, she was bent over the desk and I was taking her from behind. As we started getting into it, she reached up and opened the blinds. I'm not sure if anyone was watching, but the thought that someone might be, really excited me.
