Would this bother you?

I have alot of loose skin on my belly from my c-section and my husband always grabs/pinches it. I've told him over and over I do not like him doing that and he still does it saying he can do whatever he wants to my body. Not only am I insecure about this loose skin, but it just feels uncomfortable because that skin never got it's feeling back, like it's still partially numb but also partially sore if that makes sense, so it feels weird for it to be touched. Am I overreacting about being upset over this? Would this bother you?
