Pakistani eunuch dancer Roomia, dances during a wedding as the bride, Nazia watches the performance in Rawalpindi on January 9, 2010. Mocked, pitied and disowned by society, Pakistan's eunuchs are usually reduced to earning a living on the streets begging or prostituting themselves. Once granted a favoured status in the Mughal empire's court, they are traditionally paid to help celebrate the birth of a son, or to dance at weddings. But in Muslim Pakistan, where sexual relations outside marriage are taboo and homosexuality is illegal, eunuchs are also treated as sex objects and often become the victims of violent assault.
