I told my gf I'm a cross dresser. What now?

Hey! I just told my gf I am a cross dresser and I like being a sub and well... sure you can guess. I have for years and have a collection of clothing and a set of silicone f cup breasts. She seems intrigued and scared. I don't know what to expect. I asked her to put me in chastity and be my mistress. We haven't tried any of that yet she says she's ok with it but I feel like she's not sure. What should I do? What if I want to try a man one day? What if I thought about transitioning? Should I try hormones? Very lost please help. 🥺
