Hi Andi, welcome to Susan's. I'm transitioning in my 40s myself. There is a lot you can do now just to understand yourself more and make an eventual transition easier if you decide to go that route. The first is say is start attending a trans support group. I can't tell you how they have made me fell about myself. Also seek a gender affirming therapist. They guide the conversation To Help you better understand your gender. Both of these just take time. The next, I recommend even if you decide to not transition. Start doing laser and electrolysis for your beard. This is a crazy long process, and it's one of the biggest hurdles in transition. Plus if you wait too long and your beard turns grey, it'll take a bit longer and be more painful since laser is out of the question. Besides, wouldn't it be great to never shave again?
I hope that helps, I hope to see you in other conversations too!
