Mr. Skin, if you're not familiar with the site, is the place that catalogs all female nude scenes in films and television and the site has been up and running since 1999.
Male nude scenes, at least in America, were few and far between, but has become so rampant in the last few years (thank you HBO/Cinemax) that the Mr. Skin creators have finally launched the male equivalent, wonderfully titled Mr. Man.
It's a wonderful glorious thing
Needless to say, NSFW and good for um, 'research' purposes.
To make it interactive, are you a fan of full monty scenes?
I tend to find 'resting penis' to be boring, since its just, you know, hanging there.
