Having someone in the delivery room

Is it selfish of me and my SO to want to be alone when I give birth?

My mom and sister want to be in the room when I give birth and they say "we have no choice" my sisters even saying she don't care what my SO has to say about her being in there, she'll argue with him and get her way even if it means one of them will get kicked out which is stupid because he's the dad and has every right to be there and she doesn't.

We want to share the beautiful moment alone together , just us and nobody else. Plus I'm kind of not comfortable with the whole idea of them watching me push and looking at my vagina and seeing my naked.

For me and my SO it's a special moment we want to experience alone with no one else there. I mean after the baby is here everyone can come in but as I deliver I want my privacy.

My mom and sister are so excited about the baby and can't wait to see her be born but I don't want them there. And if I tell them I don't want them in there their going to be so butt hurt about it and be all angry with us.

I kind of feel guilty for not wanting them in the room with us but then yet again I want to experience this with my SO on our own and have my privacy. I mean damn we made the baby with no one watching so no one has to watch her come out of me right? Haha

Are we being selfish for wanting to be alone?

Any body else have/had problem ?

Add on: Two years ago my sister gave birth to my nephew and she WANTED me and my mom in the room with her and her SO. I didn't even ask she offered and she begged for me to stay. So I feel like they'll try make me feel guilty about that also cause my mom was there in her room and so was I but it's not like I had to be there.
