I agree with the other ldies that it can be used deceptively. And, i agree with the guys that how are you supposed to know what it means. You really can't call her and ask.
I would assume it means that she's willing to have conversations on more outré things. I consider myself openminded in that I will talk about greek trips, fetishes of various sorts including strap on play and role play as well as have discussions that are more dominant and involve more unusual toys in addition to the more usual toys.
But, as mentioned before, she could just say that and in reality be a simple GFE provider. Or, she could enjoy discussions about only one or two of those things. Or about entirely Different things and there's just no safe way to know other than to read her reviews. And the tricky part about that is Some gentlemen are shy about putting those kind of things in reviews.
I guess you just have to take one for the team and find out and then You go post the review!
