How Extreme Does Hentai Have To Be

How big is too big when it comes to breasts on Hentai cartoons. This is a serious question. I like Japanese Manga, but I don’t actually get sexually aroused by Hentai. I look on it more as art. I believe that good Hentai is art. It can be inventive, provocative and really help the author tell a story.

But if you do find Hentai arousing, when do the increasingly larger boobs become too large to be plausible and therefore, erm, stimulating?
