Holding a puritanical belief against the medium of pornography is detrimental to the progress of art. It is unlikely that there is a single piece of media that you have consumed where an artist working on it has not also drawn pornography. Keep calling it "trash" but it is still art.

Porn hurt you, and that sucks. But it doesn't change that you hold a very skewed and incorrect opinion on an artistic medium. Im also ace, and with that, I'm often sex repulsed. Art doesn't magically become harmful just because it's porn. It's like blaming a rock band for damaging your hearing.
