Exactly!The difference between the sexuality in good anime/manga series, and shows like Fairy Tail, is that the nudity in the good series serves an actual purpose, and is logical, while in other shows it is pure fanservice.
There is nothing wrong with sexuality in anime, but it has to be well written and must belong to the story and the characters. There is a huge difference between "intimacy" and "ecchi/fanservice".
And the fact that the sexualization of women in anime is a norm, does not make it legitimate or good.
