Karhiders discuss sexual matters freely, and talk about kemmer with both reverence and gusto, but they are reticent about discussing perversion - at least they were with me. Excessive prolongation of the kemmer period, with permanent hormonal imbalance toward the male or the female, causes what they call perversion; it is not rare; three or four percent of adults may be physiological perverts or abnormals - normals, by our standard. They are not excluded from society, but they are tolerated with some disdain, as homosexuals are in many bisexual societies, the Karhidish slang for them is halfdeads. They are sterile.
