Exposed due to poorly designed beach bathroom
There is a beach I have been going to for years, its rather small but always active. last year some people vandalized the toilets so they had to remodel them. The remodel was poorly done for a few reasons. The first is that the two sections which use to be gendered for male and female are no longer labeled. The second is the locks on the doors apparently don't work, and could never work. So to explain the bathroom design there are two side by side. The entrances are screen doors, you go in and directly in front there is a small privacy wall, you step around that and then there is the toilet in the open and the changing area.
I walked into the bathroom to get changed and locked the screen doors handle. I go in and undress I am standing there naked, I Am not at all exited so my penis is maybe .5in long, just the head. As I am digging my bathing suit out of my bag I suddenly hear giggling. I look up shocked and there are two woman there, ones maybe 18-19 and the other is older probably close to 30. They are looking right at my dick making no attempt to step outside or apologize, the older one says that she has never seen such a tiny dick. I grew hard from the comment. They were both laughing now as my 4in cock was standing up. they still made no attempt to leave. I got embarrassed and quickly pulled my bathing suit on and left. I wish I had stuck around longer but I just panicked in the moment, looking back I should have gave them more of an opportunity to humiliate me.
I did see them on the beach they were with a group of people male and female, when I looked over at them the younger woman made the tiny penis sign at me with a smirk. Otherwise nothing further happened.
Later in the day when I went to change back into my street clothes I noticed that whoever installed the screen doors never installed the latch plate so the lock can't possibly work.
