The 16th century marked the beginning of the fight against sexually transmitted infections (STIs) with the use of the male condom. However, many puzzling questions and prospective solutions have surfaced over the years in the context of condom use. In 1978, a condom riddle introduced the dilemma of a man having two condoms to use for intercourse with three consecutive women. In this paper, we will discuss the solution proposed to the aforementioned riddle, and examine its public health implications. Moreover, we illustrate the challenges involved in condom use and reduction of STI acquisition.

Sex work is an increasingly popular form of employment for many men and women around the world. Many countries have implemented punitive practices to reduce the prevalence of sex work, while others like Peru, have taken proactive steps to decriminalize sex work through government regulations and elective sexually transmitted infections (STI) prevention services. While abundant data indicate the risks associated with sex work, few data detail client narratives and insights into transactional sex. This paper provides a unique account of one man's experience in a brothel and an important perspective to better understand the intricacies and complexities of commercial sex work.
