Awkward sex??

So me n hubby haven't been having sex as much lately n we tried having sex twice the first time was just super awkward but he still got off but I didnt. N we tried again today n it's just been awkward for both of us so we stopped. N he said "it's just been bad n awkward on my part" n I'm over here thinking he lost feelings or even I did. Ik I have been gaining wait so I'm kinda self conscious about my body rn. N we did have an arguement but we got over that. So idk y it has been so awkward between us during sex lately. Do this mean he lost feelings? Or is it just cuz I'm not feeling food about myself? Any suggestions to make it less awkward???
