AIO to this or is this unprofessional?

Hii, I have never had a therapist before (longer then like 3 sessions). I decided to see a male therapist as I am trying to get over my discomfort around them. I haven’t gone through assault or anything just to clarify but have avoided men my whole life due to being that scared. I told him about that during my first session.

But my last session with him we where having a conversation, when I said about my sibling hating that I was born and I said I think it may be because of my sibling wanting all attention from family. He said “Is that the only reason you can think?” I said yea and he paused. The only thing that really makes me feel off is during the pause I felt the same kind of discomfort from men that I usually feel but haven’t with him until now. I remember thinking surely he’s not about to say what I think he is. (He did)

He said “I can think of a reason” “I think because your conventionally attractive” when I said that I wish it was any other reason because u cant change your looks he said “Yea we can’t help winning the genetic lottery.” And I feel like he didn’t really validate what I said.

I could be completely wrong in reading this weird, I don’t think he meant it in a weird way but now I am overthinking. AIO for feeling weird?
