Delivery room isn't "fair"

I'm not asking my MIL or SIL into the delivery room when my son is born, but I am asking my own mother and sister.

A few people have said that this doesn't seem "fair".

What I WANT to say in response to this is, "get naked, then down on all fours, moan and scream like an animal, stretch your junk out until it rips, and then take a dump. Who would it be fair to watch YOU do this, do you think? Get back to me."

But I probably need something different to say. Any suggestions?

TO BE CLEAR: I am not changing my mind about this. Just looking for better ways to make my decision known.
