So I (25F) have a friend (26F) I met in college. We really hit it off and have become best friends. About a year ago, she confessed to me that she was born as a boy. I was quite surprised by this but I can't say I didn't have my suspicions. Now, I know that it's wrong to refer to trans people as their birth sex, so I told her that I fully see her as a woman and this doesn't change anything. But actually, my brain just sees her as a man. I'm not transphobic and I would never misgender her, but I really wish she'd never told me. How can I possibly combat this feeling? Do I tell her? Please note that I don't hate trans people and I don't want to feel like this, it's entirely involuntary.
