Wes and Devin talk about their feelings on it some in a future chapter. Their experiences were both somewhat atypical growing up so they're a little weird overall.

I keep forgetting to say the marriages aren't exactly arranged. But if I explain it it's kind of a spoiler.

Wait, did I say Wes hated the social constructs of relationships? I'm confused because that's totally not a Wes thing. Although I'm not sure he's been in many relationships. Also, for what it's worth, I think he's bi. Although I'm not sure that comes up in the book(s) at all.
