I'd like to become a manga artist considering hentai

Well just making a story, drawing it and selling it or showing it will make you an eromanga-ka, just the issue i thinking you're getting at is where do i get discovered for the japanese audience enough to get a spot in a magazine or tankobon? Outside you printing out your own stuff and some japanese artist or publisher seeing it the only other way is entering a doujinsh con and getting word of mouth or maybe getting an interview with an editor of one of the hentai anthologies. There american and western people doing comiket and are contract artists working in anime, manga and hentai. Most of those because they move to japan to work or sweat in the long line of waiting illustrators.
