Was I sexually abused?

So we have this little thing in our town it’s called comfest I went with some of my friends without my parents and I had to go to the restroom but none of my friends did and little did I know there was a man in the stall and when I went it he locked it and covered my mouth I tried screaming but I couldn’t and all he did was take out his penis and made me do things with it but nothing was in my vagina.
