If your therapist has any gender training, they should be familiar with non-binary, but may not have as much experience as you'd like.
It isn't very hard for them to work with it, and you may have to do a little of the learning curve, but that's going to happen regardless of their background.
The first few times you see a new therapist, it's a lot of getting to know each other.
This in itself is a lot of help by way of reassuring that a good relationship is starting, one you will benefit from.
They will have a lot of questions, just as you do.
It's not unlike getting to know just about anyone, except they are concentrating on you and your difficulties, trying to put some priorities on them.
Up front and honest makes this 'honeymoon' period of adjustment for the both of you as short as possible, it is essential to the process.
This will get you closer to your goals the fastest, and with the best results.
If they don't seem right for you at all, then maybe think about a different one.
But if you aren't completely honest, and that doesn't meant just dumping everything, you'll be doing the same thing with any therapist over and over.
Stay on task, don't let it drift, don't let the therapist either. They are just people who are trying to help and have their own specialized training to help you.
Touching on having a spiritual side is fine, let them know where you are, but don't dwell on it.
Your spiritual guide is for that, not your therapist. Keep in mind they are going to lead the conversation, but you need to also keep it on track, as well.
The more information you can give them, in a summary kind of way, the faster and better they will be able to understand your needs.
In turn, you'll find that they will be more in tune with you, as you will be with them.
Low dose T is what you will start with regardless of what you say, if it is recommended.
Low dose is pretty common and anyone in the business of prescribing it should have a background, and if not, the info is very easy for them to find nowadays.
Like with any good relationship, honesty is the key.
Stay on task to get what you need and want, but do pay attention to what others have to say, both the good and bad.
If any of it becomes confusing, be sure to touch on that even more to clarify it and move on to the next thing.
Time is limited when talking to them, use it wisely.
