Uncomfortable Therapy Experience with Cross-Dressing Therapist

a few years ago I got into a very uncomfortable and possibly sexually-themed incident involving my therapist. he worked out of his home and I went there for one of our scheduled sessions. the waiting room was in the kitchen so I was waiting there. a man came out of the bedroom then shortly after the therapist came out too (male) dressed in women's lingerie. he said he didn't think I was coming to the appt cause it was raining (which doesn't really make sense to me and he never asked or contacted me about it previously. there were some other odd things that I can look back on as being a red flag tho I didn't notice at the time like him taking a Polaroid of me at times or wearing women's clothing to a session. I'm very open minded and don't judge ppl based on their gender or preferences but it seems the women's clothing thing was more of a fetish thing (autogynephilia) instead of gender confirming thing. everything just really rubs me the wrong way and I never told anyone about this but think it would be good to eventually tell my current therapist at least but I feel really embarrassed and awkward talking about it or telling anyone what happened. I guess I just wanted to write it here and maybe get advice or better understand what happened, why, and how it could be affecting me. also does this count as a form of abuse? if so what kind(s)?thanks~
