Do you want a family? It’s not too late. Kids these days would do well to have a conscientious person like you as a parent. Also seeing a child learn is underrated as one of the greatest joys in life.
No. And I never have. I would have been sterilised when I was 20, but they don't really like to sterilise young, childless women. Or sometimes not childless women. Luckily, my spouse is.
The only real thing I've kept on the table is foster children or adopting an older child. I did keep an open mind about dating men with children back when I was dating.
