This book explores the issue of prostitution in Nigeria through Joseph Fletcher's Situational Ethics, advocating for its legalization. It argues that criminalization perpetuates stigma, exploitation, and health risks for sex workers, while legalization can regulate the industry and improve conditions. By applying Fletcher's ethical framework, the study evaluates the impacts of criminalization on sex workers' autonomy and well-being, highlighting the benefits of legalization such as increased access to healthcare and reduced violence. The research reveals that criminalization exacerbates vulnerabilities, while legalization offers protection and opportunities for regulation, aligning with situational ethics principles to address these complex social issues in Nigeria.
