In a way, it can be common. Think about all the times when kids are in a rush or not fully aware of their surroundings. They might be focused on something else like getting a toy or getting ready for an activity. So, they might end up in a situation where they are naked in front of someone unexpected, like mom's friend. However, as we grow older, we become more conscious of these things and it becomes less likely to happen.
One way is to keep your mind occupied with other things. If you're constantly thinking about appropriate topics, like family plans, news, or hobbies, it's less likely that your mind will wander to something that could cause an unwanted physical reaction. And if you feel it starting to happen, quickly excuse yourself to a private area for a moment until it subsides.
Apologize immediately. Acknowledge that it was an accident and that you are sorry for the inappropriate exposure.
One possible story could be that you were a small child and accidentally walked out of the bathroom without realizing you were naked when your mom had a friend over. It was an innocent mistake and everyone just laughed it off as kids do silly things sometimes.
Acknowledge the embarrassment. Just say 'I'm really embarrassed that this happened' and then keep your distance for a while to let the initial shock wear off. This gives everyone time to process.
Having a wet dream in front of anyone, especially a parent like mom, is extremely inappropriate and embarrassing. If such a situation were to hypothetically occur, one should immediately try to cover up and excuse oneself to a private area to clean up and compose oneself. Then, it's important to keep this private and not discuss it directly with the mom, as it's a very personal and private matter.
It is generally not appropriate. Being naked in front of family members, especially in a non - infant context, goes against the norms of privacy and modesty. In most cultures, there are clear boundaries regarding appropriate levels of clothing and personal space within the family.
Always make sure you are in a private space. If you're at home, lock the door of your room. And be more aware of your surroundings. Don't engage in such private activities in common areas or places where people might unexpectedly walk in.
I'm not sure exactly what kind of situation you mean by 'caught mom'. It could be something like catching her singing and dancing in a silly way when she thought no one was watching. Once I caught my mom trying to learn a new dance move from a video on her phone and she was so into it that she didn't notice me. It was really funny and endearing.
You could try to keep a bit more distance from her in the future. If you're all sitting together, make sure there's some space between you. Also, be more aware of her body language. If she seems a bit uncomfortable or like she might have some digestive issues, it might be a good idea to excuse yourself for a moment.
It is completely inappropriate. Nudity is a very private matter and should be reserved for appropriate and private settings. Being naked in front of friends violates basic social norms and boundaries of privacy.
