First time was in early 2020. I was in Amsterdam so it was kind of a "when in Rome" situation. While that experience wasn't great - girl was insanely hot but it was very transactional - I had more positive encounters elsewhere in Europe later on that trip and during the two that followed...
I've done two duos (one in Toronto, one in Montreal) and just booked a third for my next trip to Canada. The condom switching is a drawback but I like the focus of my sessions to be BBBJ anyway, so it's less of an issue for me.
