Person B: I attended my first sex party at 18. The first parties I went to were with my best friend at the time (also a sex worker ) and a casual partner who was also dating that same friend! Going to parties seemed like a natural extension of testing out the boundaries a bit more in my personal life. Woman A: I started about five years ago, when I first started to explore open relationships. How and when did you first start going to sex parties? Were you dating anyone at the time or did you go solo?
