My therapist who specialises in LGBT+ is a female but she has had a lot of experience with both transmen and transwomen.
I don't know if I had a preference of a male vs a female therapist, but right now I'm content with my therapist. I agree that just finding someone you're comfortable with is important, regardless of their gender
I do agree it's good to have a therapist who is knowledgable and objective and whatnot, again, regardless of their gender.
