think i had an orgasm (or several)

I've always been a virgin and never even masturbated until I'm in my twenties, so I'm unfamiliar with how orgasms feel like. Yesterday I used a vibe on and around my clit, and while I usually shy away from intense stimuli, I decided to tough it out and see where it went. Very quickly there was pleasure building on top of pleasure, then it peaked, then a rush of liquid came out, then it was over. I still felt horny so I tried it again and again, and the cycle repeated a good 5 times. They all occurred within 10-15 minutes of each other, went as fast as they came, and I recovered quickly (could stand and clean up with no issue). Am I right to assume that this is a type of orgasm that I've experienced, and if so, how can I make it last longer and feel so good I can't even move after? Fingering feels alright but I'm still working on being able to take multiple fingers, so it might take a little while before I can use a toy that's long enough to reach the G spot.
