Is this POCD, Pedophilia or anxiety? Please answer thanks!

I'm a 20 years old guy. Months ago, I was looking and browsing through normal porn because i was bored. Out of curiosity. I decided to search CP.(At that moment, I never thought it is illegal and i thought CP is teenage girls which involves no kids. No kids came to my mind when i search for it.) I HAVE NEVER HAD ANY SEXUAL ATTRACTION TO CHILDREN AT ALL DONT GET ME WRONG! I decided to search on it because i wanted to see how it is like. I don't get turn on by kids. So i just went google and search the images for it and i saw a image in the category. You know images category which consists a lot of images. So i browse through and saw the first picture without clicking on it and felt disgusted because it is a kid at the age of 1 to 6 with a guy(No obscene or sexual picture is on it,only a guy and a small girl) knowing that my search is related to it. I ignored it completely. Afterwards, I decided to look around the images and saw 1 more picture. I click onto it which link to a forum due to my curiosity and I stared for a minute and i immediately freak out and closes it. I saw the image with the girl performing a fellatio with a guy. It is not a kid but perhaps a girl who just reached her puberty because there's hair in her area. My reaction was stun by looking at it because she is pretty and how could such man do this on a young girl. I'm not sure im turn on or not. Apart of me having seen her face which looks like an adult which cause me to turn on abit. Other part having seen her as a young teenager disgust me totally. I have been worrying for days why i search such stuff due to my stupidity for looking at it. I have been constantly checking whether i get turn on by looking at kids(imagining them naked) recently which cause me to be anxious and nervous around them because i don't want to be a pedophile. Even i don't get turn on by them, my mind is telling me that i'm turn on which causes me to have intrusive thoughts which sucks. It hard to get rid of. When i'm masturbating to normal porn looking at a hot adult. Suddenly this intrusive thoughts of kids come in my mind. I have to stop masturbating and freak out. I have to relax awhile and focus on the normal porn. Last time i have never have this thoughts when around children(although the image i saw is not children). It is only after seeing the images which makes me worry so much.when going to sleep, i tried to recalled the image very carefully. I experienced a mild erection and i start to panic and scared. Is it groin response? I know this is very serious and look down upon on and i felt extremely remorseful for searching something like that due to my stupidity. Any kind advices? Is this pedophilia OCD or anxiety?

It's ocd and nothing else. Have you spoken to a therapist who specializes in ocd, and also discussed medication?

It's just your anxiety
