DO I HAVE HOCD! PLEASE HELP I'M SCARES

I am a teenager, I have had many girlfriends in the past and still lokmin up until a week ago, here's why.
When I masturbate I usually watch lesbian/straight
Sometimes I like 'freaky stuff' things in not used to or isn't my cup of tea
So I watched gay porn and it was like I was watching lesbian or whatever same result.
I am romantically/sexually attracted to woman, but ever since I watched that gay porn, o started to worry I was gay!
My history was littered with gay tests, all saying I'm not gay, or saying , porn doesn't affect my orientation, but that didn't do it for me. I kept diggin and digging, and as time went by, the thoughts got worse and worse.
To the point in where, when I watch an Instagram video and there's a guy in it; I get thoughts saying he's hot, 2nd they repulse me, I also get sexual thoughts and those repulse me aswell.
I went through my porn history and counted 1 by 1 ( I don't usually delete) which porn is gay and some straight
And by last month, I've only watched 2 videos of gay, but I couldn't even count how much lesbian and straight I watched
All this showing me I'm most likely straight BUT still getting these thoughts
Please tell I'm not gay, they've gotten so bad I'm tearing up and messing up with my sleep; I keep worrying anything I do looks 'gay'how I walk or sit An d i can't stand it please tell me I'm not gay
I cannot imagine myself in a romantic relationship with a man
