ISO other fellow millennial DINKs?

My fiancé (34M) and I (34F) are DINKWADs (double income, no kids, with a dog) and are getting married next year with no plans to procreate in this lifetime. We’ve both lived in the city 10+ years and have a solid group of friends but we’ve sadly reached the age where our childfree life choices are slowly distancing us from other friends who are getting married and having kids.

We both want to continue to have an active social life, so we are essentially ISO some more childfree friends.

TLDR: Does anyone have any suggestions on how to meet some fellow SF DINKs?

*edited to update ‘childless’ to ‘childfree’, did not intend to offend anyone!

For all those who are commenting that they are also interested in expanding their social circle, please hit me up directly! If there’s enough interest, I may arrange a meetup for us all :)
