I suggest you spend sometime at Kinokuniya Taka, sit down, and go through all the master photographers hardcovers (I had cleared the shelves in two weeks going through every book). There is one book call Erotic Art and another called Erotic Nude. Read them.
Finally, I totally understand your point about lechers in the name of art. Do you know why this world is so interesting? It is because we have all sorts of people, and they will still be there no matter how you sulk and complain. Note that everybody has their freedom to do what they want. It is their rights. As long as they respect (do not hurt or touch or insult) the models, things are fine. Maybe you would now hit me with "what about the mind?" Well, who cares about the mind? I bet you also think of naughty/evil things consciously or subconsciously. Does that label you as a bad person? Nope.
Be more open a bit. Have a bigger heart.
