Ah, gotcha.
I've seen that silliness and it IS silliness.
Don't be confused. They are play acting different roles of dominance and submissive. Obviously that should tell you how screwed up and immature is their image of marriage and how stupid it is for one of them to be the "dominant male."
It's a sick relationship what will fade away into acrimony and heart break. It also sounds a lot to me like TREMENDOUS immaturity, The poor women really didn't stand a chance. They'll end up on a shrink's couch wondering WHO THEY REALLY ARE.
I can love them, but ... they creep me out with those very games you're talking about, the role playing and all that. And beyond. It all gives me the heebie-jeebies!!!! Mostly I just feel sorry for them and keep it to myself when I'm around them.
Gay men are totally different from my perspective. I suppose gay men creep guys out a lot more than lesbians do! My brother once declared that he himself was a lesbian trapped in a male body -- I know, old joke, but this was many decades ago, long before I ever heard of anybody else saying that! {^) It was when he met a friend of mine who was very pretty but fancied herself a lesbian (I don't think she really was down deep, but who knows?), and he was desperately seeking a pick-up line!! {^)
