Maybe that's what it was. The ease of familiarity is not something he comes across so readily, whether it's during leisure or work. So to find himself camping on the back of an ancient aether fish-god or whatever, in a tear-drop shaped tent hanging off of a tree, sharing it with a guy wielding a metal arm is almost bizarre. He didn't expect to go around sharing his personal life with some guy he just recently met.

Also he doesn't even think that Bucky was from a time period way beyond what he thinks he's from, and is left sort of glancing over at him in silence as Bucky asks his questions. Being 'gay' wasn't a non-issue where he was from, he's pretty sure some people still have hang-ups over that, but it wasn't as big of an issue anymore.

"Well, no..." He sort of elongates that 'o', trying to be as tasteful about this conversation as he can. "I had a wife. I'm not keen on categorizing myself, but I fancy either or."

He could be bi, or pan, for all he knows. He'd just never really bothered to explore it beyond what was already available at his fingertips.
