How do you get around this challenging girl calling you vanilla?

She’s literally implying you’re the opposite of vanilla...

Your interpretation is way off. This is a positive response. For the love of god, don't treat it as a shit test. Just move it forward. Something like "Good. We should get together sometime soon"

This is not a challenge. It’s time to make her qualify a bit:

“Hope you can handle all of that ;)”
