I agree on some premisces, but not all. I do not think your sex/hormones/whatever influence if you do it positively or negatively.

It's either the nature of what you're competing in, or how is it viewed by the society at large. Not sure which yet, I haven't thought enough about it.

My two main non-work, non tabletop activities are now windsurfing and rock climbing, two activities that are split roughly 70-30 male/female. We compete the same.
