No, it is not appropriate. Such topics are very private and involve inappropriate and uncomfortable situations that should not be publicly discussed. We should respect the privacy and dignity of family members.
A story might be about the mom teaching her son to bake cookies. They laugh as they mix the ingredients, and when the cookies are done, they share them with the whole family, creating warm memories.
It can be extremely embarrassing. The son may feel ashamed and guilty, which could potentially affect his self - esteem. He might also become more secretive about normal sexual behaviors in the future.
He should first try to cover up immediately out of instinct. Then, he should quickly compose himself and apologize for the awkward situation. He could say something like 'I'm sorry, Mom. This is really embarrassing.'
Well, this is really embarrassing. For the son, he might feel like he wants to disappear in that moment. But he should know it's a normal part of growing up, just that it happened at a bad time. The mother should pretend she didn't see much and give the son privacy. Maybe later, if she feels it's necessary, she could leave a note or something to let the son know that she understands it's a private matter and that she still loves him no matter what.
No. Such stories involve inappropriate and private sexual content which is not suitable for public discussion or promotion, especially when it involves minors. It violates ethical and moral norms.
The son can quickly cover up and then be honest about his embarrassment. He might want to ask his mom for some privacy and then later have a conversation about how he'll be more careful about privacy in the future.
