My brother always likes to hug me when he sleeps, and I am embarrassed to push it away. What should I do (my daughter)

Still young. Don't think about adults! You two are brothers and sisters. If you don't resist, let him hug you. Definitely not the habit of sleeping together for so many years. Change takes time. If you don't like him hugging you like this, tell your mother that you have grown up! Dude, this is not good. I don't want him to continue like this. Your mother will take immediate action.
