I assume that when you and your wife were married 17 years ago there were words said like love, honor, cherish?
Words like this are usually used when making a vow (promise).
I wonder if your wife ever reflects back on that day and wonders why, in the past year, 24/7, she no longer deserves to be cared about like that because of a panty fetish.
She knows! You are not fooling her, just yourself.
