Eyes for all women

This concept is very common. There are thousands of books on the topic. But let me approach this from another angle for a second.

If him looking is a natural thing where he doesn't consciously mean to do it, then you nagging and criticising him essentially is saying he's wrong for being himself. Weather you accept this premise or not there is truth to it.

So rather than kick you when you already feel down about this, why not look at it in another way?

Look at it like this. He is not locked into a relationship with you, he is free to leave any time but doesn't, why?

He has the option to leave yet decides to be with you. He looks but goes home to you. This should be a compliment yet you would rather argue with him about his natural biology suggesting he is broken and needs fixing.

Let him look and know that he still chooses to be with you.

The staring would bother a bunch of us, staring pretty rude in the first place, whether or not I was there.

That has never happened to me.

Your points are valid. A quick glance is one thing. A quick glance may not be a big deal. On the other hand, staring can be seen as insensitive and inconsiderate.
