she'd get full control, can make you do anything, and you'll be thinking of her a lot more while caged, you'll be a better husband/bf overall.
just start it off as kinky foreplay and then see how it goes. it'll probably take some time for you both to figure it out anyway, just keep communicating.
worst case, you or her aren't into it and stop. best case you awaken the dominatrix in her.
you could always find some online material/guides for her to read and how to act.
