Key Social Norms Take-aways Transactional sex is shaped by deeply rooted social and gender norms in Tanzanian communities. Core norms include male provision in relationships, reciprocal expectations of sex from girls, and peer-driven pressure to achieve a “modern lifestyle” through material possessions. Relationships are often not viewed as exploitative unless there is coercion, power imbalance, or unmet expectations of exchange. Notably, girls who engage in sex without receiving gifts may be socially stigmatized, reinforcing norms that legitimize transactional sex. Effective interventions must address these local understandings and norms, not just rely on global definitions of exploitation.

Objectives To explore the local social norms influencing transactional sex and assess community perspectives on when such relationships are considered exploitative, comparing these views with international frameworks of sexual exploitation.

Methods A qualitative study was conducted in one rural and one urban site in Mwanza, Tanzania. The research team carried out 18 focus group discussions (FGDs) and 43 in-depth interviews (IDIs) with adolescents (14–24 years) and adults (25–49 years). Vignettes were used in FGDs to prompt discussion on fairness and exploitation. Thematic analysis was conducted using NVivo 10 software, combining both deductive and inductive coding approaches.

Results Transactional sex was widely normalized, with material exchange expected in sexual relationships. Community members described exploitation in terms of broken reciprocity, coercion, and power differentials. Men were seen as exploitative when they failed to provide after sex, while girls were criticized when they took gifts but refused sex. AGYW were socially pressured to conform to peer expectations around consumption and lifestyle, which fueled engagement in transactional sex. Structural vulnerabilities like poverty, gender norms, and limited economic opportunity contributed to these dynamics.

Conclusions Understanding and addressing transactional sex requires a nuanced view of how local norms frame exploitation. Interventions must engage with the community’s own definitions of fairness and gender roles, involve families and peers, and provide economically viable alternatives for girls. Programs that ignore these social dynamics risk being ineffective or culturally misaligned.
