Unajua kwa nini relationships with those kind of people do not last? No matter how liberal, forward-looking, urbanized, multi-cultural, feminist or whatever-shitist you think you are, it is always going to play at the back of your mind that your partner kisses other people for pay.
And these people are people you may know and not necessarily like.
You can't be kissing some man-whore at lunchtime in the name of an "acting profession" and come kiss me at night! Sigwes na sigwes!
