Can you look at a woman?

Well, if your with your misses, you should concentrate on her and not on other woman. I think she would notice if you weren't looking at her and she may even catch you looking at other girls which would seem rude. But I mean if you have thoughts like that keep them in your head , as long as you don't say them aloud. I don't know if alot of other young men would think that kind of stuff, but a lot of them would look to see if she were attractive or not.
