Is it normal that i masturbate remembering nasty things from my childhood?

When I was 10 or so I used to climb out my bedroom window naked and roll around in the dirt while it was still dark until a neighbor saw me and told my grandmother and I got a beaten. But to this day it arouses me like nothing else even sex with women. I turn out the lights in my apartment and think about it and immediately get hard and masturbate. It’s a high like no other.
