I know I signed up for Gaydar (which is possibly the website they coyly refer to) once when I was somewhat tipsy, but at least I didn't post pictures of my cock on the internet. Restraint, and all that. But maybe if I decided to enter politics, I might have reconsidered.
Plus, the "that's not my penis" defence cracks me up. I haven't seen the pics, but I'm guessing the subtle message is this that he wants us to know it's normally bigger.
