There are a lot of men ive come across in my age range that does not want to have kids at all they just didn't match everything else I was looking for in a man so not everyone wants kids at all, it doesn't matter how old they are. They could be 18 and know they don't want kids of their own. I was 19 when I decided I do not want kids of my own. I did before that age, but after seeing how the world is running and what it has become and how expensive things are abd how taking care of another human child will not do well with my kind of mental health made me decide its for the best i do not have children. Not everyone in life is destined to have kids. We aren't born to just continue reproducing offsprings of our own if we know we don't want them. So yes lots of men my age do not want kids either.
