I don't-I don't know why anyone would want to see my penis!It's disgusting!!!Looks like a slug eating a mushroom!!!UGH!!EWWWWWWWW!
I think it may be a modern form of individuals that get sexual excitement from exposure of their penis, in the past these individuals were called raincoat flashers, wily waggers, and etc. They would get arrested for indecent exposure and face legal problems. Now today it is safer to just do it over the cell or net.
i think they look great better then faces
Probably the same reason some women show off way more than they should. Attention. Though it's really unflattering. Even if he does have an attractive tool doesn't mean he knows how to use it. What he should be showing is a video of him using it the right way. Now that might get some attention. :)
