Thamel, District of Kathmandu (1)

In plain sight this man offers a young girl money, proposing that she has sexual intercourse with him after the show. There are an estimated 20,000 sexual workers in Kathmandu who sell their services in cabin restaurants, dance bars, doharis and massage parlours. Between 5,000 and 10,000 women are trafficked each year from Nepal to India, joining the hundreds of thousands who have already been smuggled or chose to emigrate to find work overseas.
