Where are all the childfree women hiding?

Hi all. I'm 38M and I've known I wanted to be child free since I was a teenager.

My best relationship ended because she wanted children and I didn't.

Since then I've found myself generally dating women in their twenties because they're the only options I've had. But we always seem to be at different life stages. I'm a bit of a boring bastard, I guess. I'd like to spend my Friday/Saturday night with my gf, whether that's going out for a nice meal or staying home and watching a movie with some good food and a bottle of wine. But these younger girls still want to party a lot.

What's the point in having a gf if I'm home alone on a weekend while they're out partying?

So anyway, I set up some OLD and set my preferences around the mid thirties and fuck. 50% are single mums and the other 50% is women who are desperate to hurry up and have kids.

I keep hearing about how the number of women choosing to stay childfree is dramatically increasing but I can't find them anywhere.

So, ladies of this sub.. Are you single? If yes, so you use OLD? If not, how do you date?

Any help appreciated. Thanks in advance.
