Be careful what you wish for
I completely understand what you mean, the idea of cross-dressing being a mere sexual thing does not make one sound virtuous. Attaching cross-dressing to a more noble sense of being would make life a lot easier.
I did a similar thing, not on such a grand scale, as you. In order to see if I could cross-dress for long periods of time and get used to it, I started to dress every day for a few months after I got home from work. I kind a joke to myself that at the same time I was coming home from a job where a wore T-shirt jeans and sneakers, women were coming home from their office jobs taking off their high heels, pantyhose, skirts, and blouses. They put on their T-shirts jeans and sneakers to feel comfortable while I was putting on high heels pantyhose skirts and blouses to feel comfortable.:D
I did achieve what I set out to do, I felt comfortable wearing women's clothing. Unfortunately I felt comfortable wearing women's clothing. It dawned on me one time while I was getting dressed that women's clothing provided no particular fun anymore. I took what was once exhilarating and fun and turned it into the every day and mundane. Then came the question I could not seem to answer, if wearing women's clothing was no longer any fun then why was I still wearing them? I stopped the practice of wearing women's clothing everyday because I realized for it to be fun it needed to be an occasional thing in my life.
I have no doubt that within a few days the whole arousal thing will go away you will get used to wearing women's clothing as if it was no big deal. (Drilling tasks over and over again works for Armies in all times and all places) I wish you well in your endeavor. Just remember at the end of this you will have to answer the same question I did.
