This came up rather recently didn't it?
I've skimmed through this thread and there's quote a few, understandably I suppose, getting a bit irate due to others telling them they're missing out by not having kids.
There are certainly more couples going without kids, due to choice, inability to have any from trying to late and cost being the other big factor.
However, regardless of what some say, a huge amount of women tend to become more maternal as the clock ticks so don't be surprised if it happens to you.
My wife and I are both 37 and I could list of endless amounts of couples that are using IVF or married for the convenience of having a family (which is usually the wife's decision).
As for me, I never wanted kids and was glad I had my 20's to booze it up, travel a bit and be as carefree as my cash allowed. My wife got her own way into our 30's but I've loved being a father, regardless of how fucking hard it is sometimes!
I'm now working in a different city to my two kids, 4 & 2, and it's very hard coping without them.
I couldn't love them anymore, it's a deeper emotion than you feel for anything else in your life. I don't care if that statement offends anyone, the bond with your children, if your any type of man, is your deepest and most important.
