Hi Rohan,
how nice of you to be concerned about how women feel about this issue.
First of all, it is also a very natural female tendency to look at good looking men. We do it too.
As others have said, there are just different ways of looking.
When a man notices me because he finds me attractive, and looks at me simply because he likes what he sees, or smiles or makes a compliment or says hello because of that, then I see nothing bad about this. I take it as a compliment and smile back.
Now when a guy stares at me for minutes in a row no matter the situation like he cannot control himself anymore, I tend to think "Yeah, it's okay now... Go get yourself a life, dude."
There are some guys who also look at us in a very dirty way. I don't mean dirty because sexual. I don't find sex dirty in any way! What makes those glances dirty is not the sexual attraction, it's that those guys see us as pieces of meat, as mere sex objects without any personality.
They don't care about who we are, they don't see the whole person. With them, sex is just a satisfaction of their ego, no true exchange. Basically, they just dream of masturbating inside our vagina. Their glances just mean "I want to use you like an object for my own little needs.". That's abusive, disrespectful and no compliment at all, which is why I don't like those glances.
I used to be offended by them. Now I'm not anymore, after all it says nothing about me and a lot about them. We don't have to let those guys affect us in any way.
But I won't be friendly to them, that is clear.
Love.
