Shortly after starting to date a girl, she arranged a holiday weekend for us. We didn't book a hotel, and spot rates were so high we had to share a room. I didn’t bring condoms – normally this looks chivalrous, and a shop can be easily located. But here, no. Awkwardly, she decided she just wanted to touch herself to release the heat, and I was banished, naked and masturbating, to the bathroom and its full-length mirror. Perhaps you think this story has a poetic end. But the only real lesson I learned was to always carry condoms.
