Traps, anxiety and in need of help

Hi guys, so eh, I have a lot of Issues and I believe it was finally time to talk and search for help, specially seeing how supportive everyone is in there, so first I would apologize for my English as is not my first languaje; second a warning of sort, gonna talk about transwomen/traps and some possible HOCD behavious that I have developed, so that if you are not confortable with that stuff you could leave, I don't want to trigger people who have maybe passed for similar things.
First I would like to talk about my porn experience: I started consuming porn and masturbating around when I was 11-12 years old (I'm currently in my 20s) mostly with soft stuff like female solo and lesbians, around that same time I got into anime, so if was kinda naturally that I would end up in certains things later on... I remember how I always said that I didn't like watching MxF only cuz I didn't want to see dicks (Ironic considering my current predicament), anyways, as time passed I started slowy to reduce watching porn and moved onto drawn porn/hentai/etc; I looked mostly the same single women or lesbian/yuri stuff and I basically jerk off every single day, no exception.
Years passed and slowy got into more traditional things (as traditional as pornography could be lol), but then problems started to arrive, Masturbation becomo more of a routine to me and I started to loose that "feeling" ya know? It wasn't the same anymore and I couldn't get that "high" anymore... And then it happened, I got into traps, they weren't a foreign concept to me, but maybe as everyone else it was very weird to me and I didn't really like it, I just happened to come across one someday and said "yk, for a man is kinda cute", after that I didn't know what was I thinking and started to look traps hentai just as a joke and curiosity, the first time was awful, to this day I don't know why I continued, but I did it, and as time move on, it was basically the thing that turned me the most and used more than females or normal genre.
I said that it was just a Fetish, that I was still straight and then...I started to develop some serious anxiety, like really big, watching men maked me anxious as fuck, beeing real or just draws (evidently transwomen/traps makes me feel the worse) I feel pretty bad, I started to always look at their butts or their crotch just to see a reaction or even just their legs or arms, started to feeling losing interest in girls; everything went really bad one night when I was sleeping with my little brother in his room, I stared at him and disturbed thoughts came, I feeled like shit, I couldn't sleep that night. Didn't really help at all that I time I quitted collague so I was mentally bad.
One year has passed since then, I returned to collague, but I couldn't really came across a solution to my problem, I have tried to quit porn but I hadn't been able to at the moment, had done silly things using only vanilla porn just to feel nearly nothing; aside from that, recently I have started to have thoughts about girls (being real or fitcional), thoughts like "You don't really like her", "You are just lying to yourself" and then getting frustrated when I couldn't get a good reaction on me.
With all of that said, I would like if all you could help me, maybe I'm bi or even gay and I'm just in denial, but it just hurts to be like this, feel like you have lied to yourself all these years, but I would glady accepet any comentary or help, I would probably start looking for psychology help.
Sorry for the wall of text, I needed to talk about this, thanks for reading this, I will await your responses.
