I'll show you mine because I want it to be seen.
Out of pure and longstanding curiosity, why do many males enjoy exposing themselves to others? Some get loaded on booze/drugs (or not) and run around naked. Some send photos or films of their genitals (or more) to others or post on the internet. I do not find it rude, just puzzling.
When I was 6, I looked in a neighbor's mailbox and there was a photo of a man's genitals. I was fascinated, not just by the picture, but because it was not in a letter or anything. Why? I had several boyfriends who were obsessed with their own nudity and an ex who created a clay sculpture of his parts.
Are there women who are into exposition? What does it mean?
