OP, highly attractive therapists and doctors make me uncomfortable, even when I'm not there for marital issues and just for my own items. Male or female. It's not like I think they are going to be mean to me or try to steal my spouse or anything, it just makes me feel like I can't open up as much right off the bat.
I look for the most qualified person, but in a situation where I have multiple good choices (which is usually the case for therapists and general practitioners, not so much for specialists), if I have a photo of them, I tend to tilt slightly away from any that are particularly attractive.
Just want you to feel not crazy/not alone at least.
