I think that if you've been with your partner since you were 24, that's very young to know you don't want children.
It's not for everyone. I knew since ever I do not want children.
I do however agree with everyone on not doing things because your partner wants/doesn't want them. It's up to you 100%, what you want. If you want kids, have them though it might have tp be with someone else. If you don't, don't.
We actually just discussed this with DH. We agreed that as everyone around us generally has kids we do sometimes feel like we might be missing out especially when we meet the ones with lovely, happy kids. People did finally stop saying we should have some as well. We did feel under pressure sometimes a bit to fit in. But that's not a good reason to have kids.
It is hard to distinguish between "I want a child" and "i should have a child" sometimes so I get what you are asking. For us the thoughts of children were general the latter. So a no.
At the end of the day, we are happy with our choice. We are free to move countries (as we did and are planning move again), don't have to worry about schools etc, can move anywhere. Can go on holidays last minute etc. Freedom is most important for us. We don't even have pets anymore because of the constraints.
You just have to find what you want for you, not what everyone around wants for you.
