摘要:Although Bangladesh in sexual and social relational sense is culturally conservative and restricted society, several recent studies reveal that diverse sexual behavior patterns and birth control method practices are increasing day by day in both rural and urban areas of this country. Purpose of the study was to examine and explore who and why of the partners uses birth control methods in marital, premarital and extramarital heterosexual relations in Bangladesh. Based on relevant literatures review this study reveal that in premarital and extramarital heterosexual relations male partners generally used temporary birth control methods, such as condom or coital interrupts to prevent culturally illegitimate, unexpected birth and sexually transmitted diseases (STDs). Although male partners in marital sexuality primarily used temporary methods, females usually used both temporary and permanent ones, such as pill, injection or tubal ligation to prevent unexpected birth, to extend birth spacing and enjoy marital sexual life because of women’s low socio-economic status, patriarchal family authority, and socialization and women’s orientation in social policy. Based on probability sample future studies should be done to test the result presented in this article.
