I’m 58, child free. I think it depends on the reasons you don’t hand kids ? If its just so you can party, those reaosns will likely change.
My first wife and I were on the same page, so I had a vasectomy, she didn’t need to be on the pill,.albeit her reasons for CF were differnt to mine. I didn’t want them mainly for ecological reasons, too many people on a small planet, that has only become more urgent since, so those reasons haven’t changed, if that makes sense ?
My current parter had 2 kids from a previous marriage but she had them young and they were grown up, moved away to other cities with thier own lives when we hooked up. She loves then dearly and is proud of them but has said she’d never have had kids knowing what she knows now.
I could always have adopted, the world is full of unwanted kids, no need to bring more into the world.
