If this is what orgasms are like

Sorry for tmi but I wanted to get this off my chest and see if any women have advice or are going through the same thing. I've only had what I believe to be orgasms through clitoral stimulation...although it feels good it doesn't feel anything like I've heard an orgasm is supposed to be like. It lasts like 5 seconds, and I'm not mind-blown or anything like that. Might sound weird but when I get turned on I feel like there's this build up to something that never happens, and when I "orgasm" it doesn't feel nearly as good as that build up, or like a release from anything. Like if this is what orgasms are like I'm honestly pretty disappointed.
