Orgasm??

So I've been mastrubating for a while now but I'm not sure if I've ever orgasmed. When I'm close I start feeling really sensitive and I pull away. A few times I have tried to quickly try again. I start feeling a "burning" sensation (not sure how to describe it) in my clit area and next thing I know I feel a liquid running down my inner thigh. I'm not sure if that was supposed to be my orgasm or not since I've heard how people see "fireworks" and feel very relaxed after theirs. Am I doing something wrong?
