Women getting d*ck pics

I was talking to a friend of mine at work. She's an attractive, single, forty year old woman. No pics. She was telling me that she took her son to the dermatologist the other day. Two days later the dermatologist sent her an unsolicited dick pic. I asked if this was normal and she said she's received hundreds of them. We laughed and she said she'd like to make a coffee table book of all the dick pics she's received. Kind of in the same vein as Madonna's Sex book from the early nineties.

In all seriousness, who takes a picture of their junk and sends it to someone else? At what point do in life does something think they'll be successful doing this? The only women who're into this are going to give you more than some good memories. What the frick is wrong with people?
