My wife is also accepting to a point or a "red line". After nine years of dressing probably 20/7, wig, bra, etc, the red line is toe nail polish and lipstick. Her comment is that "men don't wear lipstick". I accept her feelings even though I don't quite understand them. So I guess I'm still in the closet when it comes to my nails and lips.
We shop together for underthings, dresses, etc. She will pick out a dress or skirt that she thinks I will like. The bad part about shopping together, is that for every one item I buy, she buys three or four. That must be why she goes shopping with me. All in all, my wife is pretty good about my cding.
