The only thing that rings true about it for me is that I've encountered very few compatent young dominants (of either gender, and its fair to say there are less Dom women than men), quite frankly. Young being, in my eyes, 25 or younger. (No, that doesn't make 26 old.) In that sense I certainly haven't seen a lot of evidence of good young Dommes out there in any sizeable number.

To a degree people can change over time but I don't think there's any real set style to it based off age or gender. 18 months ago I couldn't have Dom'd (well) for anything. Now, I think I certainly could. Depends totally on the headspace of the individual. In my case I once thought of myself as a sub but as I grew in confidence and self belief under some fine guidance, I discovered other parts of myself that were in the Dom half... I am sure many switches could take a similar path.
