You could also create a family storybook. As you write down the stories together, it's like showering in the warmth of family memories. Everyone can contribute their own little anecdotes, whether it's about a family vacation, a funny incident at home, or a proud moment in a family member's life. This way, you are constantly surrounded by these family stories.
One family shower story could be when the whole family went camping and there was only one small outdoor shower. Everyone took turns, and there were a lot of laughs as the kids tried to be quick like the adults. It was a moment of family bonding in a rather unique situation.
Sharing or discussing sex stories, especially in a public place like a gym shower, is inappropriate and violates privacy and ethical norms. So, I don't believe there should be such real stories to be spread around.
