Dude I'm lost idk what to do

I've only ever dated black men. That's the only race I've ever been attracted to.. until I met my now boyfriend.. he's Native American like myself.. and he's amazing. buuuut 😒 there's one little problem. He has an average sized dick. I'm aroused during sex and he can eat pussy like a champ. But I love sucking dick, and he won't let me!! I think it's because he knows he's smaller than what I'm used to..and he's embarrassed 😕 I don't want him to feel that way and I've reassured him he makes me feel great! But I want to suck him up so bad and every time I try he gets mad at me 😟 help!! Idk what to do😞😞😞 his dick is pretty small though and I'm not trying to sound mean but.. at the same time it's nice not getting the living shit fucked out of me when we have sex..
