other women not wanting kids?

I never want to have children and yes I know people always say your 23 your still young. I never liked children as a kid I did not play family, I still do not like or want children. I hate how much pressure there is from my family and anyone who meets me to have children. I keep telling them i do not want any, its not a legal requirement to have children. I hate when people say you will change your mind.the thing that really hurts me is that my parents say your takeing away my ability to be a grandparent and continue our bloodline. I do not want to hurt my parents but if i have a child i will be hurting the child because i would be a bad parent. you should not have children unless you really want children. Anyone elce feel like they never want to have children?
