Not to contradict, but actually to ask...

I would have presumed that sissification has nothing to do with feminization per se... or even cross dressing, if the end is to look female. I thought these are acts of desire to be... and/or pride in how one looks and feels.

Doesn't sissification entail making it obvious that we're looking at a man? Aren't there components of humiliation involved and necessary? Not a "real man" and unable to be more than a pretend woman?
