This is a topic I have seen varying views from Dommes that implement forced feminization as a regular part of their lifestyle. Should a sissy be fully transformed and borderline passable as a woman or are they better off being kept "obviously a man" in their appearance. I know the views vary heavily on a case by case basis both by what Dommes wish to accomplish by feminizing their sub and by what subs truly desire. I'm pretty much ignoring the sub desires side of this since if they really want to be feminized it really takes away the forced nature of the fetish and it gets into scenarios where there are subs who wish to be women, wish to be gay, etc. and those can mask the reasons they state on the outset. So my topic of interest really is a Domme's view on complete vs. partial transformations.
Reasons a Domme would want their sub to be completely feminized:
-It gives a "there's no going back now" feel to the situation. Once it starts, things tend to keep moving forward. Panties can be hidden, full-on dressing is pretty blatant. When the transformation happens, he knows she's absolutely serious about it.
-Primping. He must now experience much of what women have gone through for years. Keeping their bodies shaved/waxed, putting on makeup, uncomfortable lingerie, nail care, eyebrows sculpting, and so on.
-Complete removal of masculinity. His male ego is no more.
-Improved aesthetic pleasure. The male figure lacks the grace and elegance of the feminine form. Increasing femininity makes him more pleasing to the eye.
Reasons a Domme would want their sub to be partially feminized but still obviously a male:
-If she is a Female Supremacist, a complete transformation is a bit of an insult for a man to be able to pass as a woman. If the transformation is only partial it can be used to parody years of restrictive feminine ideals towards women and turning him into a caricature of stereotypical femininity.
-A well-done complete transformation might allow him to actually pass as a female. If she wants him to be humiliated she is better off keeping him in the obviously a male stage as this will draw more attention and ridicule, especially if used in public.
-Increased emotional agitation. It's easier to try to be a man or a woman than it is to be somewhere in between. "Unisex" clothing has told us that it's okay for women to wear masculine clothing but that's a one-way street.
-He's not supposed to be pretty, so stop him short of being able to achieve that.
I'm sure if I could keep digging I could rattle off at least half a dozen more reasons but I'm not sure if that would lead to anything. Dommes vary a lot in their feelings on this subject (with many not wanting any feminization at all) and there's no chance of nailing down a consensus.
From my own personal standpoint it trickles back to that cycle I go through of humiliation, deeper subspace, increased arousal, peace in my soul, strong association, humiliation, deeper subspace, etc. that spirals me into a love/hate relationship with forced dressing. I can say that this cycle happens most strongly with the a partial transformation. The more realistically feminine it gets, the more ordinary it tends to feel and that leads to less humiliation to fuel the cycle.
