H cannot handle the suspense anymore, so we're going to find out the sex of our baby at the ultrasound on Friday. He just wants some time to mentally prepare, and I'm neither strongly for nor against finding out, so we're going to.
However, I'm a pretty private person, and I see no reason why we need to share that information with anyone else. For me, everyone else knows about the pregnancy, and I feel that should be enough knowledge of our intimate lives. I want to keep the sex as something between us, along with the name. I was talking to one of my brothers about the U/S coming up and he was surprised that I even mentioned we were finding out, and very surprised that we might tell people afterwards - in both our minds, it's a) mine and H's business entirely and b) it's really shouldn't be that difficult for everyone else to wait to find out whether the child has boy parts or girl parts when it's born.
However, H's brothers all found out and told everyone the sex of the previous 4 grandchildren, and H thinks MIL will whine about how we're being unnecessarily withholding. That's not really pushiness that I want to reward, for one, but unfortunately H also doesn't really see the necessity of keeping it secret and thinks it'll be more trouble than there is any benefit. He's willing to do it if I feel strongly, but I think he's afraid my articulated reasons don't make sense and/or boil down to just wanting to spite his mother. I don't really want to lie, either, and say we didn't find out in order to shut people up.
Can you guys help me articulate a more defined reason that this is or is not better kept between us, or help me see it from the perspective of others who really want to/feel they deserve to know?
