This one's tough...is it that she sees your "bizarre behavior" as an affront to God, or as an affront to her?
This may seem blasphemous, but I tend to think that 1) God, whatever that may mean to you, doesn't care that much, if at all, about what you wear, and 2) what happens between two people in a marriage is their business, and no one else's, not even the church's. If you and your spouse are kinkier than what the church would like, then that's their problem, and they shouldn't know anyway.
If she sees this as disrespectful to her and thinks she can just click her heels and have it go away, you're both going to be disappointed. Is is fair to ask you to manage these aspects of your personality? I think probably so. Is it practical just to say "after we're married, you're just not going to like CD'ing and being diapered anymore, right honey?" I tend to think not. It's a part of you, and has been for a long time, and it won't simply go away. You both need to accept that idealizing each other, and anticipating that you're going to be living with an idealized version of each other, won't work. She'll be living with you warts and all, she should get used to at least some of the warts, if she loves you.
