Do not watch this if you have a Hentai 'addiction/problem'..
Far too many triggers. FAR too many. A friend of mine was a Hentai addict, and he's also Christian, so the guilt he felt made him majorly melt down, he's actually a MODEL, and from the Ukraine. But it was the first kind of Pornography he was introduced to... and of course, Hentai is notorious with mixing violence/sex and themes of extreme BDSM.
If you're trying to ween yourself off from this type of thing, save yourself the trouble. Or, don't read (look at) the manga, and watch the show with someone else, that you *trust deeply*. Make sure to vocalize if you start feeling triggered or uncomfortable, and shut it off.
Exercising control over your addiction is *key* to handling it until it dissipates from your problem/obsession. Some Hentai addicts PREFER partial nudity as opposed to full frontal, or insinuated sexual tension, rather than just watching a blatant Hentai cartoon.
They'd rather go on 4chan and look at an img board, with girls wearing short skirts with frilly tops and seemingly impossibly long blue/pink/green hair with ribbons, than see a naked busty anime chick doing her professor. The INNOCENCE of the characters, to some, is the most sexually appealing part of this.
So to conclude the story of my friend from the Ukraine, he met & fell in love with a girl. She's IRL impossibly beautiful, a model as well, with gorgeous eyes, and an amazing body. He trusted her enough to ask her to marry him, and he lost his virginity to her. I hear tale that later on in their relationship, he had a melt-down and confessed everything to her after she found a photo of a shota girl on his desktop. They fought for a week, and he felt in his heart he was not being true to her, so he stopped looking at IMG boards, or watching Hentai. His now wife recently watched this series with him, and explicitly asked him over and over "are you ready?" (Because they BOTH missed being able to comfortably watch Myizaki and good anime together without her or him getting upset).
He hesitated, but said "yes" to his wife, and they watched it. I guess possibly he's an acceptably adaptable person, Christian, or not. And he had no problems, as he had been intimate with his wife for over a year. She told me that he didn't once "relapse"... So maybe... listen to this message if the title grabbed you.
