I don't like what she does for a living. Can I ask her to quit?

My girlfriend works as a foreign affair matchmaker. She matches individuals from different countries. Kind of like Tinder but not. I honestly feel uncomfortable that she does that for a living. I just didnít say anything because I know she needs the money. But itís bothering me how sheís like pimping girls to those older men who seem like perverts. What if one of those clients turn to her instead of the girls she matches with them? When our families and friends ask us what she does, we just give vague descriptions. Sheís not even proud of her job. Am I in place to ask her to just quit her job? Can I ask her to do that?
