There is a problem with liking children in the way you do, that problem was given a name, "pedophilia," or in your case "hebephilia" if you want to be technical.
Now, were you to like children in a purely platonic and non-obsessive way I wouldn't be saying this right now, but since you've decided to defend 'hebephilia' I must make a counterpoint. She is still very young and should not be seen as an object of sexual pleasure by older men, you shouldn't take advantage of her because of her age either, it's completely backwards.
I'm going to give you legitimate advice: Stop looking at children, tweens, whatever you want to call them for a whole month. Do not think about 'lolis', 'cunny' or whatever stupid pedo slang there is out here, it's not healthy. I want you to completely purge this vice out of your system, invest as much focus on working out, and lift for another, better purpose.
I care for you enough to type this, Anon. Stop being a pedo, you will go down a darker path the more you invest time into this vice. Do not give into your dark passions, and just lift.
You're gonna make it.
