Vaginal orgasm

Has anyone ever experienced a vaginal orgasm? The thing is, I think I have but it wasn’t the sensation that people explain it to be - it wasn’t like a rollercoaster that clitoral ones are - how with the clitoral orgasms there’s a rising sensations and then it kinda falls but it was more of a consistent feeling? Like there was pleasure but it didn’t have a definite start or finish, it was just more of a pulsing feeling and not like the clit ones at all. Anyways, anyone wanna share their experiences?
