Guys, do you often think about sleeping with other women when you're in a relationship?

I ask this because someone I work with has a girlfriend, but whenever a somewhat attractive customer comes in, he says he "wants to give her his phone number" and "wishes he could date them". It always sickens me because I have a boyfriend who also works with us, and our coworker will often say things to him like "would you fuck that girl if she asked you to?" (he says this while I'm not at work). My boyfriend always says no because he's in a relationship.
