This is the kind of thing that happens here, a change comes over her and she just gets right into it regardless of where she is. We've had to hustle her into the car and put a blanket over her a couple of times. The slightest touch can set her off, it's safer to get her alone and get her calmed down. Remember the post about Black Snake Moan in chat box? She is not as bad as Christina Ricci portrayed, but there have been moments.
There is medication, estrogen or a testerone blocker, that can help, but we both love her hyper sexuality, and help her with it.
