Can I say I was SEXUAL ABUSE (I need to know what box to check in psychologist office )?

When I was in middle school, there were a few guys, one being my “boyfriend” he was the worst. On the bus he’d usually sit in the seat with me and cover my mouth and do sexual things despite my constant protest. I used to scream but the bus driver would just tell me to shut up. So every time he’d corner me I’d say no but I didn’t put up much of a fight anymore. Sometimes there was penetration with fingers while I was pushing him away, but not very often. He’d cheat on me, pull up my skirt or my shirt so everyone could see and laugh about it and let his friends touch me as well. Made fun of my body, stretch marks and fat infront of everyone. The other guys were classmates. It started with typical slaps on the butt and running off giggling. Then grabbing, then crotch grabbing, then one guy holding me down while the others groped me. Teachers knew but most ignored it. This happened to a lot of girls in my school but most to a lesser extent Some got it as bad as me. I’m sure it was because I was very shy and afraid to tell personal things to teachers and my parents would be mad at me.

It was done by other 12-14 year olds.

There was only penetration by fingers

No ones clothes ever came off

I stopped fighting back

Was this childhood sexual abuse or just kids being bullies?
