What are some differences between males and females?

I am trying to write a contrast paper on males vs females and I am running out of ideas. Can you please help me come up with some differences between males and females that I can contrast between the two? I didn't know where to categorize this sorry.

Genetalia Muscle Mass (generally) Places of hair growth Common interests ...yeah. Pretty obvious stuff here.
I remember I was at a transgender support group with a friend who wanted to go and the person leading the discussion stated a question which I think can help you because you have to reflect on it a lot. "Besides having a Y-chromosome or not and along with it's affects, what makes you the gender you are?" I couldn't really answer it. I just said I was because that's what I would prefer to be with the mentality I have. Hope I kind of got you brainstorming.
besides the obvious? number of fall cells (yes, woman are born with more...you cannot 'grow' more), distribution of fat, HORMONES, pelvic shape, etc...
hmm, here is one to think about. Men are just not natural mothers lol...
