What is the equivalent to men looking at other girls when they have girlfriends?

I know this question seems odd, but I’m really curious… I read somewhere that one of the main reasons why women can get jealous when their man look/stare at other women they find hot is because women generally base their value on their attractiveness. This is different with men. Men usually base theirs on success… So I was thinking, what would be the equivalent to men staring at other women when having girlfriends? What can a WOMAN do, that would make men equally jealous and insecure?

Is it constantly talking about another man’s success, or just observing all these men with huge successes in front of her boyfriend?
