Is it wrong of me to not want my wife to take off her mask when she’s in labor?

My wife is 8.5 months along with our first baby. We’ve already met with an OB, and she has office visits once every two weeks. She has to take off her mask to do the exam and I feel uncomfortable with it because I’ve never really seen her chest before. I feel like I should feel closer to her but it’s just not something I’m used to. Also, I know she’ll need to remove her mask when she gives birth, which I’m nervous about.
