I don't know why a man would wish to send us a picture of his tallywacker. I voted for it being in poor taste (you know, like using a word like tallywacker!).
But some men seem to really LIKE the idea of sharing photos of their cock.
Silly men!
I don't know of a single woman who appreciates it. Unless it belongs to Rocco Sigfreddi. Then I don't wish to see a picture of it. Only the real thing!
