Was I close to an orgasm

Okay so I've never touched myself, ever I'm 16 and I know a lot people who started like when they were 11 and I just came back from the movies with my boyfriend and we have sex and everything and I've never orgasmed before, so anyways I came back from the movies and I had had this urg to touch myself, I've never had this before and when I did try before I felt awkward and weird but this time I layed in bed and just went for it so as I was rubbing my back started to arch and then I was looking up and I lost track of what I was doing but I kept going and breathing heavily and I felt pressure but a good kind of pressure but I stopped and idk why but OMG it felt so good, can anybody tell me if that was an orgasm ?
