Jamie,

I think it has to do with the perception of risk taking and how testosterone drives that. Guys, that is not a bad thing at all, it is irreplaceable.

Additionally, guys have superior spatial and abstract skills and equipment and technology gets their motors running just shy of chicks. Us girls have the benefit of using both cranial hemispheres for communication, which is why we can understand that when a fellow woman asks their man; "Do you think I'm fat?" rather then meaning "Do you think I'm fat?, as the English language would seem to imply, what women are are really saying is "I need you to reassure me that you still find me physically desirable and that I am the most fit and attractive women in the world, now hold me".

Us girls tend to be a tad more risk averse, a little bit less gear oriented, and WAY more beautiful animal & beautiful ocean's oriented. Guys will live on a cramped liveaboard to get that testosterone dive, whereas we like the land based resorts a little more.

None is better or worse, that is why we mesh so well together

I love the wee critters myself.
