I think it depends on the area/family, honestly. I try to be upfront with my nontraditional family structure early in making friends (not confrontationally or anything, just making sure to drop comments about my queerness in the conversation/references to my wife) so I/my kids won't have people they're starting to like pull away when they learn about it. My friend group involves some straight couples, some lesbian couples, some single moms by choices (straight and queer both), and a bunch of childfree people of a wide array of sexualities and relationship status. It's much harder when you're new and trying to make the first set of friends, though. Maybe just start with a small playdate with one other family, specifically mentioned that both you and your wife will be there? Hopefully you'll get a good response and once you have one friend, it's a bit easier to have confidence and expand your circle. You could even start with one of the gay couples if you know them/their kids. Good luck!
