Orgasm?

Hello I am 20 and in my first relationship. Recently my boyfriend and I have been experimenting I guess. Two weeks a ago we were messing around and making put and what not (We don't have sex though).

Last week I had something super strange happen that I have never had happen. I think I had an orgasm. I have never heard of this before until I was trying to figure out what happened.

My boyfriend and I were in his room and he asked if he could feel my boobs and I said he could, we ended up sucking them (it felt amazing). At one point he slightly bit them and then my whole body got super warm, I had that gross stuff in my underwear and I could feel it, he kept doing it (I was okay with it It felt amazing) then all of a sudden I began to feel like I going to pass out and I felt like I need my pants. I can't really explain it that week.

Does this sound like I had an orgasm to you, I did some research and it seemed like women don't usaully have an orgasm from stimulation of their breast.

What so you all think?
