Is it an orgasm?

🖤

When I masturbate I feel a wave of pleasure. My vagina starts twitching and one time I did actually “came” but I’m confused because every time I read about female orgasms they make it seem like it’s this huge thing. I do feel my body writhe and get hot but it only lasts a few seconds. No vaginal fluid comes out so is it still an orgasm? After it passes, I use my vibrator a few more times to get that feeling again but like mentioned it only lasts a few seconds. I get frustrated because I want to experience a true orgasm like the ones I read. It’s to the point I’ve cried about it. Please advise. I’m very naive when it come to masturbation. At my house sex was never a topic and I’m the oldest of 3 so I have no guidance in that department.
