The practice of anasyrma (harakointi or pyllyttäminen in Finnish depending on context) was quite widespread in Finnish folk magic. Meaning ritual exposition of ones genitals for magical/supernatural effect, in Finnish context the magically potent female one. Currently there is one spell featuring it, one that buffs pawboards by having women walk over them. However while a female PC can get her pawboards buffed by other woman she is unable to do it herself. This should change, for instance there could be seperate female specific version of the ritual (gender specific rituals would be cool in general now that I think of it).
