As far as I can tell, there's no social stigma against men being gay on their side. It's just women who don't get a choice. And Wes is kind of "ooh, shiny" about anything pretty so it's hard to tell what's flirting and sexual interest and what's not. The only person he really wants to be with is Devin, though.

Calla's backstory chapter explains a lot more, although it might need to be modified to make it clearer how the marriage process works. I will have to figure out what little hints I can add in along the way.
