Human parenting does not define us, how we treat others does.
The person who cuts my hair is 50, I know that because she told me, and has no intention of having children. She has nieces and nephews, has them around for a while and then they go home with their parents. Works well for her.
My wife and I, married for thirty so far, and we both did not want children. We have enjoyed 30 years of fur kids instead.
Everyone, including you, gets to choose how to arrange our life, both with and without people and things. That includes have or not have children.
The only right is what you feel is right for you.
Once you have children, there is not a return policy.
Make a wonderful decision and make it later in life. You have time.
