My 31M boyfriend won’t have sex with me 22F

for context we have a weird past and i used to have to beg for anything intimate.. even having him makeout with me.. it got better, kinda. everything else in our relationship seems fine but sex.. is just so… not there, and it’s frustrating. i need help. i’ve tried almost everything. i know there’s quite a big age gap but he only seems to wanna have me go down on him and he never ever does on me, occasionally fingers me but that’s it.. my sex drive is pretty high and ive been debating on this being a deal breaker or not. i’ve suggested different things but he refuses to even tell me his kinks or wanna try anything. he gets very weird when i talk about sex. i’ve asked a million times if he’s even into me and he reassures me he does but i just don’t seem to believe him. should i give up? i don’t know, im so frustrated with the whole thing.
