Hi mate. I don't know what Wattpad is but masturbating to erotic stories resets the counter. Porn is not just pictures it is also written stuff.
Wattpad is a place where just about anybody can publish fiction, and I think you can read for free? It's like any other fiction; not all of it is erotic, but some of it is. If you go out of your way to experience anything erotic, that's porn.
