Next summer, I'm going on an overseas trip with a close friend and their spouse. I was looking forward to diving during the trip, but since I'm not a good swimmer, I secretly started attending swimming lessons. The instructor was a male, and as it had been a while since I'd interacted with a man other than my husband, my body became overwhelmed with excitement and shame. I ended up masturbating in the changing room. I never expected that someone would secretly film me and use it as leverage to begin a new kind of lesson.
