How do I stop liking younger children?

I am around 15 years old and like younger children. I don't know what to do. I want someone to help me stop liking them. Hate me all you want but just know I'm trying to seek help.

I think about younger kids like 10-13 and I have had past experiences of being groomed which may contribute to it. I don't want advice like "oh just talk to your therapist about it" because my therapist is a snitch and isn't reliable. I just want someone here to help me stop liking younger kids and thinking about them in certain ways. Someone help me stop.
