I am a non-transitioner so all of this should be taken with a great big heap of salt, but I've always wondered how sexuality feels to other people. Sort of like the "is your blue and my blue the same" question. For me, it's always had some degree of detachment, for lack of a better word. As PG-13 as I can be, I don't find myself so much into what I'm into, as much as I'm into the other person being into it. What this usually means is picturing what it must feel like, putting myself in that space of being viscerally desired, and kind of vicariously experiencing it, if that makes any sense. It's part of why I'm fairly sure I'd go from being straight to still being straight, if I ever were to transition.
I'm visually attracted to women, but I wonder how much of that is true desire vs. envy. I realized a long time ago my desire towards women and the desire my peers had were not the same. I've never looked at a woman and thought, in the words of the Steve Miller Band, "I really love your peaches and want to shake your tree." It's more of, "wow, she's really pretty," like admiration rather than desire. It's also highly relationship-driven. Everything in the sexuality space for me is inherently linked to the emotional belonging of that relationship. I've never had a one night stand, never been to a strip club, and never really had the desire to do either of those. It definitely made me stick out like a sore thumb in college when I was the lone voice not terribly interested in paying a completely disinterested woman to "dance" on my lap.
I don't "want," I want to be wanted which then makes me actually "want," if that makes any sense at all.
