How do I best reply to "Why do you like me?" She says I constantly frustrate her because I don't agree with everything she says, and that I'm always playing/being sarcastic. But she's definitely into me as she was biting me and cuddling up to me all last night.

My thought was to say something like "That depends on how good the sex is." or "Who says I like you?" I could use some suggestions, thanks!
