When I was a young man, I spent a lot of time trying to figure out why I do what I do. After years of thinking on it, worrying over it, and considering all the possibility's of why I might be like this. I never did come up with anything that helped me deal with it.
So I stopped wondering why, and haven't asked myself that in years, but what I did is give up asking why, and give up feeling guilty, give up being ashamed of myself, and start dressing when ever I wanted, staying dressed for as long as I can at a time, and just enjoy the time I can.
Now my whys are more like, why can't I get my hair right, why does this not fit better, and things like that.
I figure even if I knew the why, I would still have to deal with the need, that wouldn't change, so why is the shy so important anyway?
