A situation analysis of sexual networking and sexual health in an industrial area of Gujarat, India, identified anxiety about masturbation and other semen loss concerns as major preoccupations among young men. This paper describes how the Deepak Charitable Trust addressed these concerns in their HIVprevention programme for young men aged 15 to 30. Flowcharts were used as participatory learning tools and to obtain data on the perceived consequences of masturbation, both before and after intervention activities. Research was also done on the relation between semen-related anxieties and sexual risk behaviour by DCT and two other NGOs among young men engaging in unsafe sexual behaviour. DCT advocates addressing masturbation and other semen loss concerns in all sexual health campaigns in South Asia, based on the magnitude of these concerns, their potential to confound syndromic management of ST/s and their significance as an idiom of psychosocial distress. Masturbation and associated anxieties about sexual performance are seen as health issues and discussed as such by the programme. There is immediate identification among young men, whether or not they are already sexually active, and it provides an excellent en try point for sexual health and safer sex education. The community response to these efforts has been en tire/y positive.Keywords: young men, male semen loss concerns, masturbation, sexual health, India T HE magnitude of the HIV epidemic in India is still largely unknown, with estimates ranging from four to ten million already infected. 1 Arguments that traditional sociocultural norms of monogamy and universal marriage provided protection from HIV led to a long period of denial. When the sentinel surveillance sites set up in 1994 began to show rapidly increasing trends in seroprevalence among sex workers, STI clinic attenders and women attending antenatal clinics, the need for targeted HIV interventions became urgent.2 Largely without systematic data on sexual networking and sexual health, governmental bodies and NGOs started HIV awareness campaigns.3In 1997, the non-governmental organisation Deepak Charitable Trust (DCT) explored the need for incorporating HIV prevention activities in its social development programme by doing a situation analysis of sexual networking in its catchment area.4 DCT has been working for the last 12 years in Nandanagar (pseudonym), an industrial development area of 20 villages with 40,000 inhabitants, near Vadodara in Gujarat, where most villagers are employed in 200 chemical factories. A major national highway crosses the area and large numbers of trucks stop there. The area serves as a rest point, with numerous petrol stations, roadside restaurants and stalls. Locally produced liquor (daaru) and sex workers are also available along the highway.DCT staff were trained and supervised by a medical anthropologist to carry out a needs assessment among both women and men for HIV interventions, using ethnographic research 49 Lakhani, Gandhi, Collumbien methods.
