I'm usually pretty good at keeping frame in most situations, but I usually don't know how to respond when she starts saying things along the lines of "I'm so sexy, you're lucky to have me", "Most people would think I'm a whore because of how good looking I am so you're lucky that I don't fuck other guys and I'm yours."

She says these things playfully so it doesn't bother me too much and I think she says it because she's insecure, but I can't come up with a good response so I usually just brush her off and keep frame.
