Clothing during sex...

Me and my boyfriend have been together for a while now and have been having sex for a while but when we have sex he keeps his shirt on. Yea he’s kinda chunky so am i but we’re both not that big (i only weigh 160 he’s like less than 220 Bc he’s also tall) and when we’re having sex i just love feeling on him his arms and his muscles. But idk i think he’s uncomfortable to take his shirt off Bc he’s a little chunky. i don’t wanna make him uncomfortable if i take it off for himBut i like my guys a little thick and I’m so inlove with him and there’s nothing wrong with him i just want his shirt off during sex. Any advice?
