I’m not sure what to think?

I’m a girl and I went to my friends house , a boy, and we were just chilling watching tv like friends do and then he started kissing me. I stopped and was like no. Anyway he grabbed my hand and put it on his you knowww. And I was pulling my hand away saying no and then he took his trousers off and made me give him a handjob and I Kept taking my hand off saying no I don’t want to but he didn’t listen and kept grabbing my hand. Would that even count I’m not sure if that’s a big deal or not even if it has upset me. I haven’t told my boyfriend because I’m scared he’d be annoyed and his friends are friends with that boy. What do I even do
