HELP. Should I let my MIL in the delivery room ?

Ok. So I’m expecting my first child in August. I still a ways to go. But my boyfriend and I were talking about who I wanted in the delivery room when I delivered. He got super upset when I said I only wanted him , and my mom in the room. ( like really upset ). Because he wants his mom in the room. I explained to him that I just met his mom like four months ago I’m not comfortable with her in the room but he said that I was selfish to have my mom and not his mom. Should I allow my MIL in the room even though I don’t feel comfortable her looking at me with everything hanging out ??? Please help.
