Although the history of sadomasochism now known as BDSM (bondage and discipline, dominance and submission and sadism and masochism) could be traced to the 19th century, it began to gain popularity through mainstream media in 2011. Despite the plethora of information in social media and the extent of practices in Nigeria, academic and reliable statistics are not available or are rarely encountered. BDSM has been portrayed by the media to consist of the use of physical torture, verbal and emotional humiliation to derive sexual satisfaction. This study explored the practices of BDSM activities among youths’ especially undergraduate students. A cross sectional survey was carried out in Lagos State using a structured questionnaire that was administered among undergraduate in three universities. The questionnaire evaluated participation in three BDSM categories - Bondage and Discipline, Dominance and Submission and Sadism and Masochism. Data were analysed using univariate and bivariate statistical techniques. The result indicated that there is a prevalence of BDSM activities among youths. Also, participants in the older age groups are fewer than others. Dominance and Submission records the highest frequency among others. The prevalence rate between males and females was comparable as there was no significant difference.
