You need to find a therapist/counsellor who understands gender identity. I’m not suggesting this to get you to stop, but to help you process your thoughts and how to approach this with your spouse. From what I read of your intro, you are on a selfish track. You are going down a certain path no matter what. Tread lightly and pray (I’m serious) for her to have an open ear. Don’t pray for acceptance. Think like a woman. Your wife needs to process information but the only way for her to do that is if she has an open ear. Through process and conversation, she may come to acceptance.
If she has deep faith, brushing off her convictions will do the opposite of what you want.
If there’s anything you are repulsed by but your wife suddenly takes an interest to it and couldn’t care less about your feelings, how would you feel? I think you would put your foot down and demand that it stop.
