The question in my mind is is the OP feeling some regret about not having children? Or, trying to say he is just fine with no kids and wants people to know childless couples can be perfectly happy? It’s not for us to assume the answer, but for the OP to explain his intent if he cares to. It could just be he is curious how parents feel about being parents. I’ve asked some questions along those lines.
I mention I don’t have kids when I give parenting “advice” because it is like a disclaimer. I realize I don’t have the experience of being a parent and I really believe parents know something I don’t. I also think all parents, even if I were a parent, sometimes can use or need a suggestion or example of what might be helpful to them in raising their children. It’s not about saying the parent is bad, I think most parents I meet beat themselves up about worrying if they are doing the right thing for their kids. They worry about it all on their own and want to be the best they can be for their children. I am sometimes mystified when adults seem to not remember what it is like to be a child, but maybe I would get amnesia if I were a parent too, I don’t know. I’m sure my perspective would change somewhat.
I do have regrets about not having children, it causes me great sadness at times, it comes in waves. But, I love my relationship with my husband and we have had great fun in our marriage. It’s not all mutually exclusive, it’s a complicated matter for me and many others.
I have people ask me ignorant and hurtful questions sometimes about being childless, but the people closest to me almost never do. No one pressures me to have children. At times people make suggestions, because they see me having a hard time. Sometimes the suggestions are helpful, sometimes hurtful, but I know their intentions are good.
I think partly it is cognative dissonance, people want to believe they made the right decisions in their life to help them live with their own decisions. Having kids, not having kids, where they live, who they married, we have to marry in our minds our decisions and our reality to move forward in life and be happy.
