I'm a 20 year old male and I consider myself a pedophile. I have a sexual preference for girls 13 or younger. I wasn't always attracted to them. Before I was 16, I had a sexual preference for adult women. I began masturbating and having sexual fantasies when I was 11 and they were about adult women. I would go on porn sites when I was 12 or 13 and I would masturbate to MILF porn and women with big breasts and butts.
When I was 16, I started to look at porn actresses who had small breasts and butts, and I masturbated to them and eventually became attracted to them. I later discovered loli hentai and I became attracted to lolis.
I've told people this story, they claim that porn didn't change my preferences, I was always a pedophile but just didn't discover it until I was 16. Is this true?
