Do you want to have children?

[Badger]

I'm 26 and have zero interest in having kids right now, but I'm fairly certain I will want them when I'm in my 30s. My only problem with my dormant desire to have kids is that I think having children of your own is a selfish thing to do when there are so many children in need of a good home. I fully expect to rationalize this by the time I'm ready to have kids, as well as get attacked by people who claim having children is not selfish.
