The broad category of "kteuy" covers two distinct sub-groupings, "short hairs" and "long hairs". Short hairs (សក់ខ្លី, "sak klay") are men who dress and identify as men but have sex with "real" men; they are usually married, and very few of them have sex exclusively with men. Long hairs (សក់វែង, "sak veng", also called ស្រីស្រស់, "srey sros", "charming girls"), identify and behave as women, and may use hormones and surgery to change their physical sex. They call themselves "kteuy", but may feel insulted if outsiders use this term.
