Manga

There's nothing wrong with ecchi, but it can definitely be a bit of a fly in the soup for a lot of people, especially with manga and anime. And there's nothing wrong with that, either.

I like fanservice in a lot of what I read and watch, but I've disliked it in just as many things. I don't think you can make a blanket statement along the lines of "these people are just repressed prudes" for being unable to look past it when it is present.
