"Not having thought about it enough?" shrugs Aurin. "I was so thoroughly distracted by girls that I didn't notice my much smaller inclination to kiss boys, at first."
"I dunno, maybe that sort of thing doesn't happen to you all? Love at first sniff."
"Is there a set of genders it's usual for each one to be into, or... not?"
"What about if you are attracted to some of those but wind up settling down with somebody with whom you are not?"
"...Uh, if you promise not to add any more people to the marriage, and it's not currently possible for the marriage to produce children, there's some stigma for that, but if you leave open the possibility of adding someone who could make children happen people won't bother you over it even if you never actually do."
"Are marriages normally multi-person arrangements, then? That's not unheard of for humans at home but it's usually two people."
"No sort of networky things? I have had as many as three girlfriends at once but they weren't all interested in each other and one of them had a boyfriend who the other two and I weren't seeing and so on."
"S'pose. Do married people sometimes have outside partners, then? Who aren't the childrearing type or whatever."
"But Sealing cuts that off along with the possibility of marrying extra people?"
"Some people at home say that about getting married at all. Monogamy is very popular."
"It is very much the normal thing to do in most modern Elcenian human cultures to date around, more often serially than in parallel, in one's teens and twenties, and eventually pick one person to marry and be monogamous with indefinitely. Variations include not doing the 'eventually' part, not being monogamous with your eventually in one fashion or another, and getting divorced because you picked the wrong eventually. And there are cultures - fewer now than there used to be - where they do arranged marriages."
"They can be pretty bad when there's only two, but yeah, I bet it's a lot worse if it's five people all packing up their stuff and yelling."
