The words 'inferior' and 'submissive' do not sit well in the same sentence when I read them together. It is my opinion that submissives are nor inferior, but equals and the only difference is that they enjoy doing what they are told to do for the pleasure of another.
Having said that, I would also like to mention that, in my opinion, anyone that has to 'eradicate' something about someone else because 'they don't like it' seems pretty shallow and domineering to me. Not dominant, but domineering. However, if this is a change that you wanted to make in the first place and you have no objections, then I take that back and will tell you to have fun and party on.
A person cannot just be told that they are submissive. You couldn't just walk up to the Pope and tell him he's a Methodist and have it be so. If you have the inclination to be submissive, and it sounds like you probably do anyway, then you can have that side of yourself coaxed to the front and brought forth through discipline and training. In which case, I think thew rules set forth by your partner are very good ones and will more than likely do just that. That is, if takinig baby steps doesn't drive you up the wall first. LOL
But enough from the psychology and self-help sections, let's get to the effeminization and humiliation sections:
If your wife truly wants to effiminate you and humiliate you for her own personal amusement, I reccomend the following things:
Have her buy you a corset and some really pretty knee high boots with heels. You'll look great in them adn it's really hard to forget that your someone's slut when you're dressed like it.
Butt plugs are really nice accessories for the wants-to-be-a-slut person. Preferably one that will be just a little uncomfortable when worn.
I don't know if you guys share your relationship outside of the home, but if you do, then being made to serve at a dinner party of some of your wife's female friends dressed in a humiliating and/or effiminate manner can always be great.
Spankings or some other form of discipline should be used to make sure your new teachings take hold. Depending on how open-minded and willing you are to experiement, forgetfulness could easily result in all sorts of nasty things, from being used as a toilet to enemas to whatever else you partner's devious mind can come up with.
OKay, this is really getting me going. I have to stop or I'll sit here and write a freakin' novel on this stuff. Have fun and good luck.
