too self conscious 🤦🏻‍♀️

hey everyone, so me and my boyfriend have been together for a little while now and we have had sex a couple times already. obviously I told my gfs about it and at some point the topic of “how did he take your shirt off” (or something along those lines) came up and I told them I didnt take my shirt off at all (any of the times actually) im personally vvv self conscious of my stomach/body and about my boobs and i feel insecure when I even think of him seeing my stomach or boobs. he ask me why I didnt either and I told him that and he said he understands but hes a little upset that I dont feel comfortable with him like that bc he feels that comfortable with me. idk if I should just say screw it and take it off or just keep doin what im doin???
