My wife knows I belong to several cd sites. They are posted as shortcuts on Google, and she knows my password. I have offered to show her, and have encouraged her to visit as a way of educating herself about this side of me. I doubt if she has ever done so.
A few years ago, I bought a copy of "My Husband Wears My Clothes" (I actually don't wear hers, I have my own) for her to read. I put a $50 bill at the end so I'd know when she finished. A year or so later, I took it back.
