Trying to figure out how to slowly open up to my wife about my feminine side. Any advice?

I'm a genderfluid guy, currently navigating that delicate balance of discovering my feminine self while keeping my marriage of 10 years strong. My wife is my absolute world, but our intimacy is mismatched, and she doesn't know the full extent of my journey yet. I'm trying to figure out how to slowly and lovingly open up to her without making her spiral or feel like everything is changing. Would love to hear from anyone who has walked this line. How do you start the conversation, and how do you protect their comfort while staying true to yourself?
