No, it's not appropriate at all. Everyone has a right to privacy regarding their sexual experiences. Discussing someone's past sex story in a dirty way is disrespectful and violates their privacy. It can also be a form of sexual harassment if the person doesn't consent to such a discussion.
Public places are for positive and respectful communication. These kinds of sexual - related stories are not suitable for public discussion. It can make others uncomfortable and is not in line with good social behavior.
No. Sharing such content in public is highly inappropriate. It violates social norms and can make others around feel uncomfortable and offended. Public spaces are meant for general, respectful communication, not for sharing sexually explicit stories.
Set clear boundaries. Let others know that you are not interested in that kind of conversation. Politely but firmly state that you prefer to talk about other topics. For example, you can say 'I'm not into that kind of talk, let's talk about movies or books instead'.
Surround yourself with positive - minded people who uphold good moral values. They are less likely to engage in or expose you to such inappropriate content. For example, join some hobby - based groups where people are more focused on positive activities like reading, sports or art.
One way is through education. Teach people about the concept of consent and privacy in all aspects of life, including sexual experiences. Encourage a culture of respect in social groups. For example, in schools, workplaces, or social clubs, set clear rules against this kind of inappropriate talk. And when someone does engage in it, there should be consequences, like being reprimanded or excluded from certain activities. This will send a clear message that such behavior is not tolerated.
