My little sister wants to teach me sex stories. What should I do?
It's completely unacceptable for your little sister to try to teach you sex stories. Firstly, sex - related topics are private and not for siblings to share in this way. You can gently redirect the conversation to something more innocent, like talking about school or hobbies. Also, if this behavior continues, it might be necessary to involve a responsible adult, like a parent or guardian, to ensure a proper environment for both of you.
Well, this is a very wrong situation. Sex stories are not something a little sister should be teaching. You need to stop her right away. You can say that these are not things we should be talking about. Maybe start a new conversation about a book you both like or a movie you watched. It's important to maintain a healthy and appropriate relationship with your sister, and this kind of topic goes against that.
This is an inappropriate situation. You should firmly tell your sister that such topics are not suitable for discussion between siblings. Encourage her to focus on positive, age - appropriate and healthy topics like stories about friendship or adventure.
