Sexy time as a bigger lady

So me and my new partner are coming to the stage of discussing about having sex together. I’ve had sex previously but during the breakup and now I have gained more weight which has definitely made me more self conscious about things.

My new partner has discussed that he would like me on top and to “eat me out”. This has caused me to worry and panic. He has expressed he loves my body and everything however I don’t see it and I worry that being bigger everything will get in the way and he won’t find me as beautiful If I’m on top with a stomach.

How did you girls overcome this fear in the bedroom ect.
