Can’t orgasm, it’s me or him? (Long story)

Help!!! I can’t orgasm unless it’s oral (him eating me out) Bad part is I have a feeling he doesn’t like giving head, at first I thought it was because I smell or something but right away i knew it couldn’t be that since we always take a shower before sex. Then I asked him and he said that I was his first on giving head meaning he never done it to an other girl ONLY ME. This made me think that maybe he’s shy or scared that he was unsatisfying me but I made it clear to him that I was having more orgasm when he ate me out and he still doesn’t do it as often as I’ll like. I ask for it and nothing he doesn’t do it he just go straight to intercourse. This makes me so unsatisfied b/c we have sex 2-3 times a week and in that I only orgasm once and him all the time, sometimes we go on rounds and he cums and I don’t. I think it’s me,I think it’s because I’m chubby and I just can’t find that right spot unless is him giving me oral. When we finish I just feel down, I don’t want to cuddle and I don’t want to sleep I just be laying down thinking on how bad I want to have orgasms all the time, or at least most of the time. He ask what’s wrong b/c he knows something wrong with me when he finish but I just don’t wanna hurt his feelings by saying I’m unsatisfied in our sex life, but I just can’t help to feel like he just wants to bust a nut and get it over with like a quickie. I just don’t know what to do. At this point I need help and advice on what I should do!!!!
