Response to ”i bet you say that to all the guys”?

I was texting this guy and we were flirting and he responded to my text with the sentence “hahah I bet you say that to all the guys smh”. How do I respond? Did he mean it in a flirty way or was he low-key trying to hint at me being a whore who talks to a lot of guys?
