I don't understand your point about women solidarity.Of course, women should also have several dance partners! Let me count:
3 of my 4 partners also have other dance partners.
Of the 3, 2 have their partner for practicing only.
The remaining 1 occasionally invites me to a tiny private balanced milonga.
It is quite pleasant to spend several hours dancing and talking without the stress of a competitive situation.
While being in dark about your point, I have to say that instinctively I always avoided pampering any leader and seen from outside you must say I am quite arrogant. I am a feminist and I won't give an inch to the male dominance or let them have superior favorable circumstances
