Male outmigration has been a traditional feature of rural to urban migration in India. Many of these out-migrants are married and have left their families behind. This raises the question of whether men actually abstain or seek other sexual partners. To address this question, this paper attempts to study migrants’ sexual behavior and sexual health as well as their attitudes towards extramarital sex and preventive practices during sex outside marriage. Findings from the survey of 500 married male migrants suggest that migrants staying away from their families are 3.6 times more likely to indulge in extramarital sex than migrants staying with their families. The need for more information campaigns and providing recreational facilities for migrants living away from their families is suggested by the study.
