I'll tell the full story later, but when I was 9 we went on a 2-week trip to visit relatives who lived about 6 hours away. They have a son who is about 6 months younger than me, a daughter who is 2 years younger, and they had a pool in their backyard. Much to my chagrin at the time, I was bathed with the other two kids, and - worse than that - the boys swam naked in the backyard pool. After my two weeks of being allowed no modesty, I immediately returned to being modest and thought back on the two weeks with a mixture of embarrassment and excitement.
Fast forward to my wedding reception. Our families had set up a display of photos from our birth to the present, with our newborn photos started at opposite ends of the display and progressing toward the middle where there were photos of the two of us together and a few albums on the tables. My new wife and I were preoccupied during most of the reception, but we could see that everyone was visiting the photo display and it looked like they were spending more time on my side for some reason. When we were getting ready to leave, we decided to go and see the display for ourselves. There, about halfway through my display, were photos of me and my cousin buck naked around the pool and in the tub! Then I realized that there was a full album from the trip, and there were more pool photos in it. My inner 9-year-old died of embarrassment! Basically all of my relatives, friends, coworkers, and new in-laws had seen my little pee-pee.
After our honeymoon, I asked my mother about it, and it turned out that my "aunt" (really mother's cousin) had taken the pictures, and she had sent the album to us right after the trip. She didn't show it to me because she was worried that I would have destroyed the pictures. (She was probably correct!) Then I asked her why she didn't ask me before putting them in the display, and she said that was all my older sister's idea. When I asked my sister about it, she thought it was the funniest thing. Then she told me that as soon as the album arrived she couldn't wait to show her friends. They used to look at it during sleepovers. My inner 9-year-old died of embarrassment again! In retrospect, I wish that I had known at the time that her friends had seen!
