Same here.... Me and my wife (31 and 30) do not have kids and don't want any.
We live comfortably enough and think that the are super annoying and we just don't feel the need to have them. We probably could afford kids but with some major financial sacrifices.
My sister has 2 kids and they are super annoying constantly(one more than the other). They adore me of course. I am THE Santa every year.
Also, we are atheists and my mother would not let me live if we did not baptized the kid and send it to first communion. She would either die of anger or murder me.
For example, we love dogs but do not have one because it requires a lot of time, care and we do not want it to sit alone whole day when we work.
And it does not help that my sister's husband is miserable all the time. The kids sure take a toll it seems... just an observation. Also, every friend goes away when they have a kid.
The pity thought of having to share my pc, console, steam library or whatever meaningless thing with my child makes me anxious... and I don't think it should. I know it's terrible way to think but I can't help to think what I think and to not feel any affliction towards having a kid.
So I am left conflicted. We do not want kids and do not feel the need to have kids. At the same time, it will probably kinda suck a lot when we get old since we will just be sad, alone and miserable. But I also feel that it is selfish to have kids in order to build Your elderlyhood. And in the end, You might not like Your kids, they might not like You or live in another country. I am not sure how to proceed but for sure we do not feel it... To abandon out bedroom,(would be a room for kid) limit our free time and hobbies... all of that for annoying kids who will probably hate me.
edit: tl;dr me and my wife are selfish fucks
