Numbers

I have talked about this with a couple friends before, but since I have such a large following on my blog now, I hope to get a lot of feedback as this is really interesting to me.  This is what I want you to do. Go through the numbers one through nine and tell me your first gut reaction: is the number male or female?(PLEASE DO SO NOW AS I AM ABOUT TO POST WHAT THEY ARE TO ME AND I DO NOT WANT MY PICKS TO INFLUENCE YOUR CHOICES).

1= male               2=female            3=male               4=male               5=male              

6=female            7=male               8=male               9=female

Why is it so easy to associate gender to inanimate things?  What is it about the numbers that make it male or female?  I notice for me all the straight lined numbers (1,4,7) are all male.  I put 5 as male, but really I see it as both male and female.  I would love to see your predictions and why you thing you chose the genders you did.
