Is it normal to masturbate to the comic ay papi?

I masturbated to a comic, Ay Papi, it is about a incestuous relationship between father and daughter. Does this make me a bad person? Am I a sick person? I neved had any kind of thoughts.

It was a long time ago, maybe 7 or 8 years, I was 15 or 16, I didn't realize anything until now.
