It is completely inappropriate to be nude in front of mom and sister. Nudity in such a family context violates basic social and family norms of modesty and privacy. In a healthy family, everyone respects each other's personal space and the concept of appropriate clothing.
This statement is very unclear and could be misinterpreted in a very inappropriate way. If it's a story about a mother making a sudden noise or impact in front of someone, perhaps it could mean she accidentally knocked into something or made a loud noise while in the presence of the narrator.
Definitely not. A mother should encourage her son to understand his body's natural changes during puberty in a healthy and open way. Hiding such a thing can lead to misunderstandings or even make the son feel ashamed of normal physiological processes. For example, in a proper family environment, the mother could provide educational materials about puberty to her son instead of getting involved in this improper behavior.
This is an extremely embarrassing situation. First of all, try to stay calm. It's a natural physical reaction that sometimes happens involuntarily. You could quickly excuse yourself and go to another room to compose yourself. And in the future, be more careful about your privacy, like wearing looser clothing at home to avoid such situations.
It's not acceptable. A mother - son relationship should be based on love, respect and appropriate boundaries. An erection is a normal part of male puberty, but it should be something that the son deals with privately or with the appropriate male figure or medical professional if needed, not something for the mother to be involved in hiding. This situation can lead to confusion and potential harm to the psychological and emotional development of both the mother and the son.
One example could be a mom being forced to disclose her past financial struggles in front of the family. Maybe she had made some bad investment decisions in the past and the family, during a discussion about finances, pushed her to share the details. Another could be when she's forced to talk about her childhood traumas in front of the family during a family therapy session that she wasn't fully prepared for.
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.
I heard of a boy who got an erection while watching an exciting sports game. The adrenaline and excitement in his body caused this reaction. He felt a bit self - conscious at first but then realized it was just his body reacting to the intense emotions. As he grew older, he learned to control his reactions better in public situations.
