WARNING TRIGGERING TOPIC, RAPE , STOP HERE NOW

I need help, I need clarity. I've gotten differing opinions from different professionals as to weather what happened to me was rape or sexual abuse or sexual assault?
I'll give you a quick rundown and maybe someone will know more about this than I do. This was 20 years ago. Some things just stick with ya.
When I was 15 and my boyfriend 18, my boyfriend would get me lost after dark and ask me to preform oral sex. If I did not he would plead, and try to convince me to. If I still would not he would make me get out of the truck and he would leave me alone in the dark. Darkness is my greatest fear and he knew that. He'd come back for me min's later. (which felt like forever) Then if I didn't do what he wanted he was going to leave me there and not come back. So I would do what he wanted. This went on for 9 months, 3-4 times a week. I CAN'T GET INTO WHY I DIDN'T LEAVE, WHY I STAYED. TO DIFFICULT TO GO THERE AT THIS POINT. But he used to touch me in the most inapropreiate (sorry my spelling sucks, wrong ways) ways which I did not participate in except waiting for it to be over.
My question is: Because we never had intercourse does that change it from rape to sexual abuse or is it still rape because I was forced to into doing something of a sexual nature I didn't want to do? OR Is it sexual abuse or sexual assault because I eventually concented (against my true feelings) and we never had intercourse and I allowed it to continue over a period of time?
I just want a label. I don't know why it matters. It want change things. But for some weird reason it does matter. I think the correct label would simply put my mind at ease.
