"I've really never understood the business... of sending these pictures to women."

Can someone please explain to Mark Schmitt — and everyone else with this comprehension problem — why some men send pictures of their genitalia to women?

AND: Here's an even more awkward effort by a Blogginghead to talk about erections. I especially love the way this clip — which I edited to enhance the humorous effect — begins with the diavloggers being all out of synch talking about how lovers can be out of synch. (Warning: the phrase "morning wood" pops up.)
