SHY IN THE BEDROOM??😬😓

So me and my S/O have been together for 2 years. We’re young so we’re pretty sexually active for the most part. When we first started dating we were both in shape. Long story short he’s still looking great and has a fine ass body🤤 Just a couple pounds added. Not such a big change 🤷🏻‍♀️On the other hand, I have PCOS and I’ve gained about 80 lbs (food & lack of working out)☹️ I don’t look horrible compared to how I was before but I don’t look as great in my eyes. He says I’m “fine asl” and so on and I believe him to some extent just because of my boobs, ass and face🤷🏻‍♀️💯 I let him suck on my boobs when we’re intimate and obviously we have sex but I get shy sometimes to have the lights all on or keeping my shirt off the whole time. I’ll stop before we do a different position and get my bra and shirt back on. He’s the only man I’ve ever been this “comfortable” with (well before the weight) and I want to be a little more confident because overall confidence makes people more attractive. So could someone give me some tips or anything to help. Also some new positions or things to kink stuff up?? We always just do missionary regular or he’ll put my legs back & we do “doggy style” lol .He really wants to give me head but I don’t shave 🪒 100% everywhere 24/7 lmao so I’ll tell him no besides the fact of being shy and not wanting him to say I taste like play-dough or something 🙄 trust me, I’m honestly clean asl but I’m not going to use any scents besides organic things and moisturizer💯 I don’t want to push his head down when he’s kissing my thighs because I don’t want to seem desperate and I’d just want him to do it himself or ask me, but after all this time of being shy I’m not sure how to make things go along. Also how do I make him talk to me during sex. I mean not about bills & tv shows lmao but to talk to me more intimately ❤️ not so much as “dirty talk” he doesn’t really do that and neither do I. He says some things that are good/okay but I really want him to talk more so it feels as such . Like making love . More than fucking 🙄(sometimes) Some advice would help. Please no negative comments💙

***EDIT*** I am currently losing weight and eating better, I have been for almost a year now. I’m saying ive gained almost 80lbs overall but the weight isn’t leaving overnight obviously💯🤷🏻‍♀️ so I was wanting to know how to be more confident in the mean time and in the long run.
