X factor

What answer do you give to the question 'how many ex's do you have?' I asked for the question to be re-phrased to be more precise and clear but the chick ran off saying that i'm the 'playa' type! All i wanted to know was did she want to know the number of chicks i've slept with? the number i've slept with more than once? the number i've slept with for more than a month? the number who were single when i slept with them? the ones my famo had met? the ones i had met their famo?
What merits a chick to be called an ex?
