I was just replaying BioShock Infinite in the area of Battleship Bay. In the middle area (where you claim Elizabeth), there is a wagon shed next to the lifeguard chair. A man is sitting on the steps of the wagon shed and I don't remember what he says exactly, but he quasi-admires Booker's physique and requests that he put on some shorts that are in the shed (like those girls hitting on Booker) and he says something on the lines of "You look like a man of physical prowess. Maybe we should talk sometime."
I was kind of wondering about this whole issue. In this game, they discussed other religions (and atheism), races, and classes under attack by the Founders, and was wondering why they left out homosexuality since it was present in both BioShock 1 and 2. I don't think it's an issue. I'm gay but I think that they included some homosexuality in Infinite. What do you think?
EDIT: ALSO, in the raffle area where the Ice Cream vendor is at by the Possession Hawker, there is a shady guy in the corner asking if you "prefer any port in the storm?" That is sailor dialogue for docking your boat anywhere you can. He then ends with, "You follow me?"
