That is your right to say you don't want to have children for so many reasons. We can not say you are wrong because you have your own thoughts which we don't know. You should search for a woman who doesn't want to have children and explain why you don't want to have children. Maybe most women can not accept but I believe some women can accept your reason so although that is difficult, you can search for the right woman.

We don't know where you can start to find that but you should search by yourself and follow your path. Someday you will found the right person who want to live and married with you and accept your reason.
