I have never found out and am not planning to this time, either. First baby I knew was a boy and was right. Second baby, I'd been really wanting a girl before I got pg, so I figured that's what I got. Wrong, but not a big disappointment. Third baby, SURELY this was my girl, now. My boys wanted a sister, and I was just certain I'd have two boys and a girl, anyway. He's a boy. I would say I was more shocked than disappointed. I had really felt like I was going to have this little girl - who never showed up. I had weird thoughts like, "Okay, now where's my other one?" 
It really seemed like someone was missing. But, my sweet little boy was PERFECT. I had no negative feelings towards him whatsoever, and looking at his sweet face made me feel much better every time. So, while it wasn't easy to have a set idea of who was coming and have that baby NOT show up, I did find it helpful to have the REAL baby there to focus on.
This time, I considered finding out (but almost certainly NOT sharing the news) for my own sake. I have found it hard not to have some notion of whom the baby is with each pregnancy, though I am working quite hard at being very open to the idea of either gender this time.
For me, this time I have a strong intuitive feeling (rather than the "logic" of the last two) that this IS a girl. But I know that if it IS a girl, after all, I will love the finding out part even more at the birth. And if it's another boy, then I'm hoping it will be easier to deal with at birth, rather than having to lie to everyone who asks what we're having, simply to avoid their "awww, so sorry" type responses.
We're going to be thrilled, regardless. We will be disappointed if it's not a girl, but we will STILL be thrilled with our baby boy.

Your emotional selves are used to finding out...it's part of the way you've always done pregnancies. In an instance like that, I would think waiting + worrying about the sex would be really difficult. I'd definitely find out the sex through ultrasound.
