Fear of two boys...

We learned this week that we are having twins! I'm excited, quite nervous but I'm realizing for some reason I have a fear of having two boys. I'm just curious if anyone else had a similar fear and how they got past it. I think maybe this fear comes from my older brother - he was a bit of a hot head when he was in middle and high school. And quite the womanizer before he met his now wife. Much better now as an almost 40 yr old.

Just would love some feedback on how anyone else got past their fears of having two boys or two girls.
