Have you considered that the same is happening to everyone? It's just what people that want to be perceived as in power do. It is very normal in any other company outside of IT/engineering (I worked in a building materials company), regardless of gender. I've seen women do it to men, men do it to men, men and women do it to children, etc.
> men don't look at you
More often than not they don't want to be "seen checking you out" (either because of fear of your reaction, or because of their SO's reaction). And many male engineers are simply shy with women.
