If you are having a hard time with your Ts appearance, could it be that it has less to do with attraction and transference, and MORE to do with consistency?
You are used to seeing your T the same (apart from how they dress) every week. In your case, that includes the fact that she wears glasses.
Then, you turn up to a session and she now has contacts.
That would bother me, i hate change and need consistency. I never had consistency in my life before, so it's very important to me now.
