LOL OB.
You know something. I think this "Brain Rewiring" needs to be in focus. Here is what I think. It may be bullocks to some, but here goes.
I believe their is a natural given to all situations we, as human's, find ourselves in.
If we are outwardly male, we are treated, nurtured and brought up a certain way. Most of our attitudes are natural given what the "Man Up Stairs" has bestowed upon us. I am not trying to be "Preachy" or "Bible Thumping" but I suppose being truthful in my beliefs. But, being born female or male, society has raised us to fit in that particular mode. In ancient times, and I suppose even into today, there was a reason.
Men are more suited for hazards, not only in body strength but in aggressiveness. We had no time for frills, we hunted Sabre Tooth Tiger's, Wooly Mammoths for food as well as for clothing. But the needs of Society at that time dictated that. Just like it dictated that women to take care of kids, etc. I know, sounds like being a chauvinist male, right?? But if everyone would simply calm down, and think about it, I believe many peeps would agree.
Having said that, diversity is also necessary for many reasons that are obvious, and some might say "The Man Up Stairs" did just to keep things interesting.
I really have no Idea why being many years a sort of a prototype male, I started to Cross Dress. I spent many days wondering, pondering, thinking that very worry. I played American Football since I was 12, heck, I was good enough to be scouted by 4 - 5 colleges. But fate intervened and I badly separated my shoulder and it bothered me physically even to this day.
I believe, that when things happen, we all adjust to our new situation. If we start feeling like we are female, we adjust. Rather that is internal rewiring or not, who knows. But I think it is just us trying to do what we perceive we should do under the situation dictated by our new appearance and perceptions.
So, don't look at it as "nesting", look at as feeling free enough to do what you feel you should of done all along with out the restrictions of being "male".
I hope this rambling does make sense and not preachy or minimalizing what we all go thru in different amounts and stages.
