The literature, activities and announcements on board harp on these stereotypes, and while no one was outright homophobic, it was generally assumed that everyone aboard was "normal", ie straight and aligned with the gender binary.
In the middle of our cruise, there was a game show, based on an actual TV game show, called "Love and Marriage", held in the theatre. It was here that Tats and I elected to challenge the somewhat stifling straight culture that surrounded us.
Wedged in between two newlyweds and a husband and wife who had been together for over forty years, Tats and I representated "mid range" (over five years and under 20). We were also the only lesbian couple, and -- I suspect -- probably the only LGBTQ couple they've ever had on the ship's show. As a result largely of this latter fact, we found we gained considerable fame and notoriety; for the remainder of the cruise we kept getting "recognized" wherever we went. This consisted largely of people coming up to us with a big, friendly smile and telling us how much they had enjoyed our performance, and the occasional person yelling, “sing in Russian!“ across a room at Tats, because of a response I had given to one of the questions asked during the game show.
While it was a little disconcerting to be thrust into the public eye like that, it was in some ways a not altogether unfamiliar feeling. As a parent of monozygotic twins, I've become accustomed some level of notoriety (this was especially true when Alex and Simon were small and more easily recognizable as a “pair”).
