Well, I don't think it does.
It's not as if you are giving the same place in your life to another woman that you give to your partner. You are noticing, maybe admiring, the beauty in someone else.
Of course there is discussion to be had about open relationships, but I'll just assume for now you want to commit to one partner and are thinking this means it's bad for you to ever look at other girls (since that's what your OP said to me).
How would it really diminish your relationship with your partner? I don't think it would. For instance, the few times I do notice a good looking guy (and it's really not something I do constantly, just not how I am naturally) it doesn't in any way diminish what I feel for my bf. I'm not thinking about cheating on him. I'm not somehow saying the other person is better than him.
So why do you
think that once you have a girlfriend you shouldn't look at other girls? Can you spell out the reason(s)?
