She was considered edgy/controversial from day one where I live. People were very prudish back then, and the mere fact that she showed off her bare midrift and belly button in photos/videos/perfermances was enough . She was very sexual in her dialogues on the Virgin Tour. Talking about her "box" and making moaning sounds in front of teenage girls. In the Open your heart video she had a boy at a peep show and kissing him in the end. That too was considered controversial. From 1987 to 1989 she was considered more PG and there were talks that she had softened after Whos that girl, but then in 1989 when Like a prayer video was released there were no doubts that she always was and always would be a controversial artist. That is my expirience and opinion.
