I got in trouble with this when choosing a therapist 3/4 years ago. Chose the pretty woman subconsciously, when a male would’ve been the one who could probably understand my issues best. Recognized my error, and corrected it after a few sessions.
As for doctors, I go with whoever has the best credentials. I don’t go as often as I should, so I need someone who knows what theyre doing. Not worried about looks.
