POCD or pedophile?

I really need help. I'm a 16yo male and I'm confused if I'm really a pedophile or suffering from pocd. About 4 months ago I stumbled upon a picture of about a 9 year old under dressed and I masterbated and thought really nothing about it. I then started to worry that I might be attracted to young girls. I started masterbating regularly and I would feel terrible afterwards. I started researching what is a pedophile and I thought I was one, but then I realized I only got these thoughts when I was alone or bored. I never have urges to touch a kid because that's gross and i know it's nasty. I can't imagine murdered having sex with a young girl. Note that for awhile I stopped and I started back being intrigued by poemrn of older woman and I had a girlfriend who I loved and I didn't even think about younger girls. Then I saw a younger girl, probably about 9-12 and I was aroused I masterbated. I then started worrying that I might actually be a pedophile. Then I started feeling really bad and contemplated suicide. I hated that feeling and I never get aroused from looking at a kid now but I still feel like I'm a pedo. I know that I would never touch a kid and I would never have sex with one, but my mind keeps saying" you know you like this and you want to" and it's killing me, I tested today to see if I would have a response ( I didn't look at CP, that's gross) but I didn't get an erection but a felt a little something down there. Im really starting to think I'm a pedophile, the thoughts won't leave me alone. I literally think about it from the time I wake up till the time I go to sleep. I get a weird feeling in my stomach and I get shaky when I see a kid. I just want to be normal and not have to worry about this. I don't have a problem getting girlfriends, I still find girls my age attractive. I keep testing to see if I like young girls. I tried masterbating to one and it didn't feel right, I then tried masterbating to a girl my age but I didn't really get a major climax ( sorry for the graphic ness). I keep getting this same picture in my head of me and a little girl and I hate it and want it to go away. I think it's gross but my mind keeps telling me I want it but I know I would never touch a kid. This is ruining my life. I have a great social life and was never abused as a child. Please help me. I would like to add that I went through a period where I thought that I was gay and I basically did the same thing where I watched gay porn to see if it ariused me. I found that I wasn't and I stopped thinking about it.

Don't test. Do Not Test. Seriously. Stop testing yourself. If you are a paedo, you are feeding the urges, and if you are POCD then you are messing your own head up more and more each time you do it. Stop.

Do you have other obsessive-compulsive traits or routines or ways of thinking?
