Interesting thoughts on Crowley. I don't know enough about him to be able to speculate on his sexuality in an informed way, but what you say makes sense. Either way, whatever his orientation, it's still pretty clear in his writings that he doesn't see the feminine as something as equal and central as the masculine. What bothers me the most is that he took his archetypal ideas of male and female and believed they also applied to actual human men and women.
I think this is an egregious error, spiritually, politically, and intellectually. It's one thing to take certain fundamental energies one encounters in the universe and to label them as "male" and "female" in order to try to understand and work with them, to use the terms as a sort of metaphysical shorthand; it's another to equate those in any overt way with males and females as biological individuals.
I take no issue with setting up a system in which "male" = active, initiating and "female" = passive, receptive. It's another thing entirely, however, to go on from there and to say that men always reflect traits which are "male" metaphysically and women always reflect "female" traits. The metaphysical and the biological are two different things, and the same terms in each system refer to different things. They're not equivalent. It's an error to think they are. Each of us has both "male" and "female" qualities within us, at least when one is using the archetypal definitions of those words (and possibly the biological definitions as well, but that's another story for another time).
I don't mind the Empress being feminine and the Emperor being masculine. Symbolically, that makes sense. But I think it's incorrect to think that on an individual-by-individual basis, women are like the Empress and men are like the Emperor. Both can be receptive, creative, and generative, and both can be authoritative, vigorous, and aggressive. Even cliched gender stereotypes reflect this: the "catty" woman and the males who are the "dreamers" and "artists." You don't have to be male to be a fighter, or female to be a nurturer. To think in that way is deluded--in Crowleyan terms, or at least how I would interpret them, it's being stuck in the thinking of the old Aeon.
Nor can one even extend archetypal male/female qualities to the bedroom, beyond a certain point. (It should be noted here I'm not intending to exclude non-hetero sexualities, but am focusing on male/female sexual interaction because it's the source of the kind of archetypal thought I'm discussing.) Sure, the archetypes reflect the sexual mechanics. That's where they come from. (It seems most human ideas arise out of our fascination with our own sexuality.) But even then, the dynamics of submission and domination, the dynamic interplay between giving and receiving, is not pinned to gender. Women are not passive receptacles, any more than men are not receivers in the sexual act. If the man did not receive and the woman did not give, the sexual act could not take place.
Unfortunately, Crowley seemed all too ready to proceed in this kind of thinking, extending his ideas of the metaphysical male and female to the biological, social, and political realities. He seems all too ready to see real-world gender differences as the same as differences between male and female in metaphysical systems. It's flawed intellectually and speaks to some deep-seated inner blindness. All that said, I wouldn't want to go back and make Crowley any different than he was. The systems he came up with, though tinged with corrupting influences, are brilliant and functional. Of course, no system for explaining the nature of reality,the universe, and consciousness is ever going to be "complete" and "accurate." They're all approximations. So it's silly to want to throw out a system because it's flawed, if it's a functional system. And I find Crowley's ideas and systems to be very functional and helpful as I ponder metaphysical questions and work with the gift and burden of a human mind. So while I think it's important to note and be aware of the potential shortcomings of a particular person's vision, I don't see this as being grounds to dismiss it as invalid.
