I think I have a mild ual obsession but I'm freaking myself out?

Every time I hear the word pedophile I get a groinal response. It's just a subtle one but I just wish it would stop! I've pretty much identified pedophilia as the worst thing ever and it's like my subconscious is trying to make me feel like something I'm not. I don't prefer children, I don't fantasize about children, I don't want to have with children, etc. I think about older guys, guys my age. A guy I like right now is a couple years older than me. So WHYYYYY do I keep freaking myself out. I get really uncomfortable around children. If I look at a child for too long I scare myself and start asking myself, "Why am I staring at that kid?!" It's so freaky. I don't understand....I just want these thoughts to go away!!!!!!!! I wanna go back in the day where I never even knew of pedophilia so I would have never even thought about it today. HELP!
