Why, in Islam, men and women do not cover their bodies in the same manner?

The difference between men's physical structure and that of women is an unquestionable axiom to all people, simply because men's swimsuits differ from those of women in the West. A woman completely covers her body to ward off temptation, but has anybody ever heard of a woman charged with raping a man? Women, in the West, go on demonstrations demanding their right to have a secure life free of harassment and rape which they lack; however, we have never heard of similar demonstrations held by men.
