Those who are single and hesitant about having children later, how do you choose your partner? (I explain below)

Good morning,

I am a woman of almost 31 years old and I wanted to consider myself child free but I realize that I have moments of serious doubts on the question. I am single and I want to find a lover. Except that this childish question completely blocks me because I really don't know which man's profile to take (imagining that I go through dating sites). Because some put “wants children” directly on their profile. I also don't know if we should address this question straight away because not knowing it can really be blocking for the other person too, whether it's a man who wants it or who doesn't want it. I have the impression that being undecided on this question is blocking my romantic encounter...

How did you deal with this question if there have been people like me, or if you are like me today, what do you do?

Thank you in advance for your answers 🙏
