Transactional sex is not sex work but refers to non-marital, non-commercial sexual relationships motivated by an implicit assumption that sex will be exchanged for material support or other benefits. Most women and men involved in transactional sex relationships consider themselves as partners or lovers rather than sellers or buyers. Conflating transactional sex and sex work in intervention design and funding may be counterproductive, as interventions designed for sex workers will not reach people engaged in transactional sex.
