Haven't had an orgasm

I have sex with my partner almost every day 😊 it feels good and all but I just never have had an orgasm. I talked with him about buying a vibrater and i made him feel bad cause i got him thinking he's not good enough... all i do is moan / make noises but thats about it. .. like i hate that i kant seem to find out what turns me on or what gets me to orgasm .. any advice?
