So I did tell my psych but I was told that they can't treat me because I don't have a diagnosis.

My question is who do I go to to get one? They told me my pcp should diagnose me, but I do not have a pcp. When I get a pcp, should I tell them over the phone that I am looking into hrt when I set up my first appointment? Should I go straight to an endocrinologist instead? What's the assessment like? Do they ask about attraction? Will I be seen as less of a man, or not a trans guy, because I like guys instead of girls?
