Well I'm married but have zero plans on reproducing, so don't know if this counts.

Some male friends used to make comments all the time, like "don't wait too long because you'll probably end up wanting them and then you'll be too old!" Love that one. My family and in laws have made some comments like here and there like, "doesn't seeing little kids make you want one?" It was happening fairly frequently and I eventually snapped and it wasn't pretty.

I eventually had a rational sit down discussion about it and was met with all sorts of questions, like why don't I want them now and such. I just said "because I want to own nice things and have a lot of sex and no kids. Anymore questions about my personal life?" It stopped the comments and questions real quick.

Now people don't make those comments and they seem ok to not bother me about it.
