hah! Be careful what you wish for.
I expressed a desire to wear panties for sex as a dressing up thing many years ago. My wife wasn't too impressed at first.
She got into it after a time, then said I should get my own knickers because I stretched hers, and I built up a collection.
Then about three and a half years ago I went to my underwear drawer and she'd thrown all my male undies out. She tells me She has an emergency pair in case of doctor appointments, but I haven't seen them, and have exclusively worn thong panties since. Since then I have become semi-feminised, but most of the evidence isn't obvious to a casual observer.
