This is just an observation, mind, and I may be biased as I'm a woman but I consistently have found in the workplace that women are happier to do documentation/project management than men.

This matches my experience exactly. The last two project managers I've worked with have been women, and they've been fantastic at doing the documentation and organization that would drive me crazy if I had to. And it wasn't their formal titles; just as you said, they assumed the role because they saw that it needed to be done. The first one liked it so much that she got PMI certified and now has a much better job.

Would it be positing to tentatively suggest that men don't generally like to do things that they don't think they are good at

I don't think anybody does. But it may be more than that; I'm halfway decent at technical writing, and I don't like it at all. Not sure why.
