i think she seems super ditzy and immature, but i don't think she's said anything to necessarily imply promiscuity.
now, if she had said that she likes to get gangbanged by multiple black guys or have trains ran on her or something that would a different story. but she hasn't even said anything of a sexual nature.
honestly she sounds like a 12 year old. she probably just has a crush on some black guy and is overly excited or something, idk. it all seems pretty innocent though.
