Suppose, for a moment, your SO was in to the sport of farting to a musical tune. You still love them, but watching them and being near them might make you feel uncomfortable. You understand so you are willing to cook beans and provide the sheet music. Is think if she is willing to support you as much as she has you need to realize that she can still love you without a lot of involvement. She trusts you enough to know that you can enjoy the activity on your own. The only thing, you need to keep her involved with the other parts of your life...don't let the freedom of dressing make her feel like attention is being diverted. I think I would shy away from using her clothing except maybe the odd time even if she offered it... accidents happen and if she doesn't want to be involved, the constant reminder when her clothes are moved might become an issue. The fact that you can talk to her about it is good maybe in time she will decide it is okay for her to become more involved... for myself, I'm not sure I would want my SO very much involved even if she knew.
