I've never wanted children, ever, in my life. I was always (and still am) faced with smiles and "Ah, sure you're still young, all you need is the right man" type responses (or even worse, "I bet you'll be the first to have kids/You'll have the most kids out of all of us!"). I find this really condescending. I'm 23 now, and I feel that if I still don't ever want children now, then I still won't in 5-10 years time.
I just have no maternal instinct whatsoever, and find ways of avoiding interacting or holding my baby cousins, and kids in general. I started babysitting last December, and the whole thing has completely dissolved any tiny notion that maybe one day I will change my mind.
So, anyone else here that would rather never have children?
