I'm a man and don't want kids. I've found out that most women who say they don't want kids change their minds after a while...
Only girl I ever been with who legit didn't want kids was 100% focused on her career trying to accomplish greatness in a field of natural science... Let's just say those women (and very ambitious women) are rare but do exist. Even then, I've seen articles on top CEO women who sleep 6 hours a day and shyt and work all the time, and most of them have kids.
