Inappropriate touching

no

What are the rules on inappropriate touching at School? Sophomore year a boy touched my behind and I didn’t tell on him, now I’m mad at myself for it. My mom always tells me to tell her if someone’s touching me but I was too scared to. I just told my sister,brother, and 2 friends now. It happened when we were walking in the hallway he touched me 3 times. I think I didn’t say anything about it because I didn’t want to believe it was him and I had a crush on him. Looking back I would of told on him. Now I’m scared to go to school if I see him again. He’s very popular and has a lot of girl and guy friends. I’ve seen him grab someone’s waist before and she seemed scared of him after, but they’re friends so I think they were joking.
