We tried something similar. We took pictures of each other's private parts so we could see what our bodies look like to one another. For example, I can't see myself from the same angles my wife sees me at and vise versa (sp?).
Yuck, my junk is not pretty. But it was fun. Make sure you destroy any pictures you don't want discovered by accident.
We have also set up a camcorder on a tripod once. Hot Hard Body p 0 r n stars we are not. I had no idea how silly we look.
