How can I get past anxiety of having my fiance seeing me in labor?

I just want him to always see me as sexy and not screaming in pain with a baby coming out. All the mess of labor is gross. Esp after when my stomach is a deflated stretchmark ridden balloon. He is insisting that he will be fine and wants to be there for his baby to be born. Ugh. I just want to spare him. Has anyone else felt this way? What did you do? What was the outcome? Will he be the same after? My ex was fine when I had my daughter. I was more comfortable with him. My fiance is a perfectionist though.
