boyfriend issue

okay so me and my boyfriend have been together on and off for a few years and a few months ago got back together again, but recently i feel like he only really likes to see me to have sex with me? we go out on dates but he always wants to get physical in some way afterwards, and we hang out lots and get on really well but i think he has such a high sex drive and it’s so hard to deal with. it’s not that i don’t enjoy it, but i feel like i have to force my pleasure so that i don’t upset him. i have tried to tell him that sometimes i don’t feel like having sex and that i just wanna chill and enjoy each other’s company, but he always gets annoyed and says it’s strange that i wouldn’t wanna have sex with him unless i didn’t fancy him anymore?

i just don’t know what to do about it anymore because it’s making me not want to see him as much because i feel so lazy and like it’s so much effort and he will just be grumpy if i don’t have sex with him?
