Sexual Abuse?

Diana
I was in a car with a guy. Long story short we began to make out and I didn't mind the kissing however he wanted more and as he took out his penis I was kind of scared. He started to push me down to him and I said "Really? No I don't think I'm ready for this" but he just said " No no you are" and shoved my mouth onto his penis. I couldn't really do much because he was holding me down....I was uncomfortable and he was not gentile at all. I was in shock and couldn't believe that it was happening. As soon as he finished inside my mouth with no warning...I instantly left and began to cry in my car. I don't know if it was because I was in shock or felt sexually abused. How would of you guys felt? 
I was 17 at the time and the guy was 19.
