So here’s my idea for the first Group Challenge:

Take a close up picture of yourself. There shouldn’t be any way of identifying yourself from this picture, but it should be something that could be considered a dirty picture message if it were sent over the phone. Which means clearly seeing your nipples or the head of your cock or whatever you choose to capture. And just to make sure no one cheats, you have to write your screen name (or initials if you have a particularly long name) somewhere clearly legible on your skin.

Thoughts?
