Find Out the Gender?

So we have a boy. Found out the gender early and had a reveal. This will probably be my last. I don’t want to find out the gender because...

A. We already have everything and will decorate the room black/white natural. We can add a couple of little girly touches afterwards.

B. I want to avoid gender disappointment. Even though we’d be happy with 2 boys we really want a girl this time. I can just focus on a happy pregnancy instead of the sex.

C. I think it would be fun.

Hubby is mad and wants to find out now because he just can’t wait. He says it’s his decision too. If he finds out and I don’t he’ll spill the beans accidentally and piss me off. What do you think we should do?
