How to replace p#rn with something healthy?

I just feel bad watching nsfw videos and im not sure if its normal and sometimes they make me feel sick watching. IM 19 is it normal to have become curious about nsfw stuff? it just annoyed me and im not sure if is should change, i would like to replace my "addiction" with something normal or healthy. if your wondering i come from religious bloodline but dont really adapt to church and such.

What would you advise?
