Was I assaulted?

When I was in grade 3 (8 years old) there was a boy in my class who would pick on me. Everything you'd consider normal, he teased me and poked me during class.

The thing is, sometimes he would also kiss my back and arms when the class was dark and we were sitting on the carpet. This was the thing he did that I disliked the most.

I kept it a secret and even lied a bit because I didn't know what to do at that time. No one knows anything about this to this day.

I only had to deal with this for a couple of months before people noticed I was uncomfortable around him and they made sure to keep him as far away from me as possible (they just thought I was uncomfortable because he picked on me)

I had also thought nothing about it until a couple of months ago. I am a bit older now, and I think what he did to me was wrong. I have no one to ask about this, especially since I have since moved away from that area, so could you please help me figure this out?

I don't want to compare my story to the other horrible stuff that has happened to girls my age in the past, but this has been bugging me.
