First time masterbating

I just masterbated but for like a minute. I did it very quickly. After like 5 mins I felt a liquid feeling passing through my vag. Also my body felt hot and my whole vag and legs got so tight. Then all of a sudden I started to shake and started gasping. Outta know where I exploded with a clear liquid. Did I achieve an orgasm? Also the whole body getting heated and that whole liquid passing through my body would happen if I drank coffee or water or any drink. What does that mean?
