Rape?

I met up with a guy that I’ve know for quite awhile. Weve always had this flirtatious relationship, but nothing has ever come out of it till now. Anywho we were at his place and things started to get heated. We got to the point where all clothes were off except underwear. When he started to take off my underwear I panicked. I told him to stop that it just didn’t seem like the right time. He told me that this is what we both wanted and we weren’t stopping. I tried to push him off but he’s a big navy guy. He kept insisting that I wanted to do it that I just didn’t realize it. I kept asking him to stop, but he just kept going. I just simply decided to stop fighting once he pinned my arms down. When we were finished he blatantly said “see I told you you wanted it, you even had an orgasm.” I just kinda grabbed my crap and left. I cried all the way home. I mean is he right is it rape if I had an orgasm? I’m sorry I’m sure this is so silly to ask and stupid, but I’m just so confused. 😔
