suggestions

Soo I've been in the committed non-relationship for over a year. We love each other we really do, but I can't seem to have an orgasm with him. Like it's not about what he's doing he is great but my body won't let me. He almost made me once and I said don't stop and he changed what he was doing....and he never really goes down on me, which is my fault because I make him stop so he will have sex with me because it's honestly more of a tease....any suggestions on how to make myself finish? I've been faking it the whole time and he loves it but I'm not enjoying it as much as he is.....and I feel like if I use my hand he will feel like he's not doing something right😕
