My classmate wants to rub my own dick. (13 year old teenager speaking)

So I am a 13 year old student in grade 8th in school. My classmates were talking normally. At first, it seems normal but it's NOT. Here's how it began:

When I was sitting alone, I didnt want to talk with anyone. However a classmate just grabbed their chair next to my school desk and started talking. We all were having fun talking until THIS.

My classmate wants to "RUB" my own dick. I'm not joking. This is the first time something happens like this. Fortunately, he didn't do it but he asked me of my dick's size. I told him 5 inch. THEN HE WANTED TO RUB MY DICK. Luckily that didnt happen because the teachers were near. If that happens I'm quickly moving to another school!

He planned to do this on Sunday. The good part is, next week is school break. After the break it's final exams. I'm scared that my classmate might be lying and suck my dick or fuck me. I'm 13! My school is horrible asf!

Let me know what did your classmate do to you in school down in the comments.
