Sexual harassment

Dictionary meaning of “harassment” we all know. It is asking for doing an unwanted thing. It is not the simple meaning of the word, which is sought for here. I am looking for clinical/psychological reasoning, why the sexual harassment is applicable mostly to women and not men. Any sort of sexual approach from a man whether it is a comment or touch on the woman’s private parts under most of the circumstances are unwanted by an woman unknown to her. Conversely, similar approaches to a man by a woman (though very rare) are mostly not unwanted. Laws are made to prevent sexual harassment to women not to men. Prostitution profession is meant for women mostly all over the world because it is remunerative to them. This is because women feel the pain of harassment and men feel the pleasure and so they are paid for the pain and the pleasure the men get. Let us admit that sexual harassment is applicable mostly to woman. This is a fact, a reality. My question is why this sexual harassment is discriminating between man and woman.
