I don't have kids either. I'm the one where at every family get together I get asked, if I'm married yet, if not where's my boyfriend, when am I going to have a boyfriend, do I have kids, when am I going to have kids and so on. I don't let it bother me too much anymore. I just tell everyone that I've made the choice not to have children, they then ask me why whats wrong. Nothing wrong, just I've chosen not to have any. My sister has four and I'm completely happy being an aunt.
I can spoil them and send them home. lol.
