Cumming. And orgasm different?? How?

Nina

Does cumming and orgasming feel different? How do you tell them apart. I’m new to this whole type of thing, and I was rubbing. My clit and it started feeling really good and then all the sudden my body got tense and it felt like I was pushing out if that makes sense. Was that an orgasm or did I just cum??it lasted for 5 seconds..
