Another reason could be related to control. Your sister might be a bit of a control freak and sees this as a way to have power over you. She might not fully understand the implications of forcing you to live as a girl and just be focused on getting her way. However, no matter the reason, it's not right if it makes you uncomfortable.
First, you should communicate with your sister about how you feel. Maybe she doesn't realize that this is making you uncomfortable. Try to express your own identity and preferences clearly.
One possible reason could be cultural traditions. In some cultures, there might be certain superstitions or practices that force a boy to live as a girl. For example, if a family has a series of misfortunes and they believe that having a 'female - like' son can change their luck. Another reason could be the result of family pressure. Maybe the family has always wanted a girl and decides to raise the boy as a girl, forcing him to wear girls' clothes, engage in girl - like activities, etc.
I'm not sure about this specific story. It could be a very unique or made - up situation. Maybe the sister had some strange ideas and forced her brother to dress or act like a girl for some reason like a prank or as part of a family game.
He might initially feel very confused and resistant. But some boys may gradually adapt in order to survive in that situation. They may learn to play the role that is forced upon them while secretly longing for their true identity.
It could also be that the sister is trying to prove a point about gender equality. By making her brother experience what it's like to be a girl, she wants to show that there are no big differences between the two genders. However, this is a rather extreme way to do it.
There was a boy, Ben, and his sister, Ava. Ava was obsessed with makeovers. One day, she had this wild idea to give Ben a girl - like appearance. She didn't really give Ben a choice as she pushed him onto a chair. She started with a foundation that was a bit too light for him, making him look a bit ghostly at first. But she continued, adding mascara to his lashes which made his eyes look huge. She put a headband with a big bow on his head and a pastel - colored dress. Ben felt really strange, but Ava was so proud of her 'creation' that she showed him off to their neighbors, who also had a good laugh about it.
Once upon a time, there was a boy named Tom. His sister, Lily, was really into fashion and makeup. One day, she decided that Tom needed a makeover. She forced him to put on a dress, wear makeup and a wig. Tom was reluctant at first, but then he found it kind of fun to see himself in a different way. In the end, they took some pictures and had a good laugh together.
Well, there's this boy, let's call him Jack. His sister was obsessed with makeovers. One time, she caught Jack just lazing around and declared that she would give him a girl makeover. She made him wear a dress from her closet, tied his hair up, and used all her makeup skills. Jack protested at first but when he saw how different he looked in the mirror, he couldn't help but laugh. His sister had successfully turned him into a 'girl' for the day.
One possible reason could be a magical curse. For example, in some fairy - tale like stories, an evil witch or wizard might cast a spell on a boy to live as a girl as a form of punishment or just for their own amusement.
