POCD NEED HELP (urgent)

I have a problem because the other day I was on the internet and this image about a girl that looked like young really was attractive to me (I'm 16) and I thought. No way? Why? I have stopped liking these kind of girls since a long time ago. I started really obsessing about whether or not I was a pedo and wanted to cry. I then got so teased by my thoughts that I started fapping and the fact that she was a model even though se turned out to be 12 made me more aroused but I did not enjoy it. When I was fapping I felt like all the excitement I felt was like from all the stress and obligation (so to speak) and I didn't really enjoy what I was fapping to. I then just fapped to something normal to finish. I got really worried, I don't wanna be a pedo and I feel ashamed to have thought of that as sexy or attractive even though I don't think it was real. It also used to happen when I had HOCD at very extremely rare cases. I seek for reassurance. I don't wanna be one of those ######6 pedos that like regret it after ######6 children and stuff. When I saw her and got aroused I felt as if it wasn't really natural, I didn't enjoy it at any point, only my boner was the only "good" part I guess. I don't wanna be a pedo, please. Help. I don't wanna be a ######6 pedo what did I do to deserve OCD or pedophilia I'm tired of this. I'm not happy having these thoughts or experiences.

After all of this happened I looked at the pictures again and I felt no attraction. I felt as if the girl was only really attractive for being her age, but I don't think of it as attractive for me or sexually arousing either.

This is similar to my situation, the arousal feels fake and doesn't really hold much weight at the time. You don't sound like someone who would hurt a child and you should keep remembering that.
