For those of you that waited to know the sex until baby was born, why did you do it?

Tr

This is the route my husband and I are taking. He doesn't really care either way but I've been content deciding to wait because I don't really feel the need to know. I think the biggest thing is that finally getting to meet/know baby when they are born after a hard labor makes everything worth it, and you don't go through periods of sex disappointment. What were some of your reasons?
