Is my wife being unreasonable

We used to both sleep naked, but for last 2 years my wife has had me wear sexy nightdresses for bed. She still sleeps naked in the summer but wears pyjamas in winter, I am not allowed pyjamas but can wear longer warmer night dresses if she considers it cold enough. On weekends and holidays I must wear sexy knickers under my male clothes. During the week I give her orgasms whenever she wants, which is most mornings and usually 2 or 3 evenings we will have an early night where I give her lots of attention and usually 3 or 4 orgasms. Most weekends I am allowed to make love to her on Saturday nights or Sunday mornings, occasionally both. Today while I was at work she threw out all my male underwear and says she wants me in knickers full time. I wouldn’t mind but I go to the gym most lunch times and there are no changing cubicles in the mens locker room, just one communal changing area. She has also told me I get far to much sex and she wants to move that down to once every 2 weeks and then once a month by next Christmas. I was ok with the way things were, I would have liked a bit more sex, maybe twice a week, especially considering how many orgasms she has, but I was accepting of her wishes. With these new demands I feel she is being unreasonable, but she has said there will be no sex for me until I agree to her terms. I told her I won’t give her any more orgasms but she just says she will use a vibrator until I agree.
