After 1 month still dont know its HOCD or Im gay..

Hello, please if you read my story, than give me some answers. It would mean lot to me. Im 22 years old male. Always loved girls, had crush on girls etc. Never thought I might be gay before.
So, about 1 month ago, while watching porn a thought popped into my head. "What if I'm gay?" That made me anxious, immediately opened google and searched for answers. (Can someone suddenly become gay? how I know if Im gay?) . The first few days was the worst, read forums and if I read something that I dont like(for exemple someone found out that he is gay when he was 20 years old) than that made me anxious. The thought was always in my mind, I had no brake. Did some of the symptoms of HOCD. (I did not know HOCD exist back than). Checked nude girls, lesbian porn. Almost watched gay porn, I just couldnt start it. I was anxious that I might like it, so I closed it. Since than If I watch porn, Im watching only lesbian...
Than I found on some forum HOCD, read its symptoms and I told myself, thats it, I must have HOCD. That made me feel better... for a short time. Than the thoughts came back. The voices in my head told me, that I cant have HOCD, because I never suffered(or I did not know about it) from OCD before or they told me I just want to believe I have HOCD..
I have fears that I like guys(not sexually, but if I see a good looking dude I think im attracted to him, and thats scares me.. also lost attraction to girls...) If im in a party Im afraid to look around because I fear that I will notice someone and I will like him. Checking out girls(ass,boobs etc.) still, dont know why. To make myself feel better or because I like them..
Im anxious type, I always have things I worry about. Sometimes I fear Im ugly, Im watching myself for hour in mirror, making videos and photos from myself etc... than next month I think I will lose my hair and if thats gone than some new problem comes..

So what you think? Can I become suddenly gay after 22years? Wouldnt I realise it sooner?
Can I suffer from HOCD if I never had OCD before?
Can it be HOCD If Im not doing checking? (not looking at gay porn)
Im doing things I believe are symptoms of HOCD. Im arguing with myself in my head, looking back in past and tries to find things that can prove Im not gay, looking in forums for help etc.

no one can help?

Hey,

for me the turning point in my battle with HOCD was the realization that, whenever a girl entered a room my conciousness was drawn (without active awards, it is an automatic response) towards her and I tried to impress her to catch her attention. This never occured with men. I concluded that this meant that I was instintictively heterosexual.

Do you maybe recall some similiar pattern in yourself?

"Can I suffer from HOCD if I never had OCD before? "
yes, though I believe that you probably have other anxiety issues you may be unaware of.

Haha, thats me three years ago. Dont worry, today I have 100% recovered. I went through CBT and also (and this was a major part) changed alot of my social life (I felt very lonely back then, which stressed me out) and now got a stable life (job, friends, hobbies).
