Guys do it too in the new dating world. I have a friend who I work with and she is 45 and drop dead gorgeous. She is recently divorced and young men tend to be attracted to her. One night we are in this nice bar when a younger guy who was 28 struck up a conversation with her. They exchanged numbers and he left our table. About 15 minutes later she gets a text with a picture of this guys pee pee. She promptly shows us and we are hysterical with laughter and he walks up to the table during this moment and told us he had over 300 selfies on his phone and asked us if we wanted to see them. We told him no, but he proceeded to pass his phone around anyway..the other pics were not of his member, but of him standing in front of the mirror, sitting in a chair, his car, etc.
It truly amazes me what people show each other on their phones. The under 30 or so crowd have no inhibitions at all.
