Pjz99, the only way my preventions can be confirmed or not is by keeping an eye on the thing. I certainly will...

Miss Nancy: Yup, there are. It's a market in itself, aimed to an adult audience as soon as it gets kinky at all. It's also labeled as such. Manga with gay overone exist for younger audience but without the bits that are not fit for the youngsters to read yet.

Basically, there's manga for everyone if they look for it,, with factors in mind such as gender, age, professional field, social category, favourite sports, general hobbies, even tastes in food sometimes. I'm tempted to say, just like plain text books :) For example, can you imagine a manga about a guy and his 8 years old kids fishing, with nothing else happening in the whole chapter except the three of them staring at their line, waiting for something to take the bait? Well... it exists. And making it so it doesn't even get boring to read is quite a feat. Yet, it's working.

Somehow this has always amused me :)
