When are you having kids?

I got married yesterday!! As soon as I announced it on social media I had a lot of people asking me when I’d be having babies. I’m VERY vocal about how I think kids are gross and how I would NEVER have them. So even as a joke, it’s not funny. ( I think some people were serious though.) Why is that the first thing someone asks when you get married? There are much better things to ask to someone! I don’t get it at all!!
