You know your stuff, Cochonette!
I actually think there is something to "masculinity" and "femininity" beyond social constructs. I think what I experienced to inspire this post was the beginning of understanding myself in terms of shamanic androgyny. (Not the same as being transgendered, more like the original - indigenous - meaning of "two spirit person.")
It's a spiritual blending of gender energies, sometimes expressed in orientation but not always. Gender is basically social but then it is also a distortion of a genuine balance of dualities (think the yin yang symbol). From my understanding and experience anyway.
So the stuff that inspired this thread happened, I looked into it, and then later I had a sudden emotional experience which was actually my androgynous expression swapping - so my feminine side came to the surface and my masculine side is doing its action-oriented thing on the etheric level. My gender energies could still switch at various points throughout my life.
So I thought this was an issue of sexuality when it was really the prelude to being conscious of the spiritual component to these things. And I do still admire the physique of both biological makeups, but you're right I've never been "in love with" a female. Not in a romantic sense.
But in terms of the debate that goes on about preference, labels, etc., I think you just shared some valuable information
