what would i do?

may sound harsh, but i'd walk. doesn't matter how you want to dress it up, essentially she wants someone else in her bed. I wouldn't put up with any b.s. about having a special sexuality etc, etc. we all experiment when we are young, but when it's time for a committed relationshiip, you grow up and are faithful or risk never being able to really deepen a relationship.

if i wanted a superficial relationship with a fuck toy - i'd stay. but if i was looking for a mature lasting relationship - i'd say hasta la vista baby and go find someone who wanted the same thing.
