I wouldn't try "introducing it in the bedroom" anytime soon unless she brings it up. Many women draw the line at that.
I've posted "my way" before. I brought my wife along slowly. She always wore a "sack dress" around the house and I complained about it. She said it was comfortable so I said "I want one too." She bought me one and I started wearing it. She asked me to order her some Ahh Bras from eBay. When they came in, I was opening the package and she said "Are those my bras?" I said "No, my name is on the package." and put one on (and left it on). I said "Now I need some panties to go with my new bra." She said "Go get some out of my dresser drawer." so I did.
To make a long story short, she gave me a couple of her old blouses and I started wearing them around the house with my bra and panties, then I started stuffing the bra, we started buying me clothes at retail stores, I bought real forms, a wig, shoes, padded panties, jewelry, etc.
All this took place over a couple of years. Each time one thing became normal to her I pushed the line a little further.
This worked for me, it may or may not work for you. I think it's easier than the shock of seeing one's husband turn from male to female overnight.
