Orgasm?

Okay so I was having ‘fun’ with my SO. I had my bullet on my clit and a vibrator in my V. After a while of messing around, I was getting built up. I then realized how extremely wet it was down there, my SO said that I probably came. But isn’t orgasming and coming the same thing? I didn’t feel the release of pressure and there wasn’t like an explosion. I did start to have tear up towards the end. Did I come without orgasming? Also is there a difference between normal discharge and cum, like would the look different? I’m so confused.
