orgasm VS cumming?? 🙀😦💥

tonight me and my boyfriend were hanging out and we dont have sex yet so he was doing the usual... he went down on me and i came once (or so i thought) and then he fingered me and i came again (or so i thought) and then i felt done and tired. it felt good but not MINDBLOWING like most girls say orgasms are. Everyone says orgasms are so amazing but i just thought everyone was hyping them up too much cause they are cool to me but not like mindblowing i guess. i kinda thought it might just be how i am too since everyones different... so afterwards hes telling me he wants to give me an orgasm and im like ??? is that not what just happened AND HE STARTED TELLING ME THERE IS A DIFFERENCE BETWEEN ORGASMING AND CUMMING FOR FEMALES. and that i just came i didnt orgasm. i looked it up on google and saw some stuff but nothing really i was looking for. He claims cumming is like a mini orgasm but orgasms are like mindblowing in comparison and its like a whole out of body experience. usually when i “orgasm” or “come” (or what i thought was me cumming) i feel a lot of adrenaline and like buzzing in my body (theres no way to put it in words) but he claims he hasnt made me orgasm yet? but apparently boys cum and orgasm simultaneously everytime and its like super hard to make girls orgasm and they can only orgasm once, but they can cum a bunch of times in a row since its not as “intense”. ive never heard about this and im just trying to figure it out HAHAHAH

basically, my question is: is there a difference between orgasming and cumming? if so can someone explain to me what it is and if you can tell a difference when you come or when you orgasm.
