Hi Dee!
This is a very interesting observation, even though it came to you in dream form, and I expect you will have more. Embrace every one of them!
Being "heterosexual" all my life, I think often about the future and am well in tune (I hope) with my changing body and thoughts about physical intimacy. I thought I was certain that I would always remain attracted to female post surgery. I'm not so sure, today. Some men, although very, very few, I encounter, trigger that "what if??" sensation in my mind, and in my heart. And it is an awesome thought, too. I still, lean towards woman preferably, at this stage, but the point is I don't have a clue where I'll end up post surgery. One thing for sure, I have no doubt it will be awesome!!!
I also have had thoughts that I would be limited to only "those that gets what it means to be trans!". My therapist made a statement to me: "it's just body parts". That made me really think, and I guess it is now gonna boil down to the "person" that I become attracted to, not the sex. May ultimately be male, or female, or MTF or FTM, or non-binary, who knows?? It should be someone that we both can grow further with each other.
I am now free, and becoming more so every moment.
