I'm 34, single with no kids
We never had kids either. I sometimes wonder if I would have been a good parent or not, and what old age will be like without any kids. But then, I've had my mortgage paid off and have been debt free for years, so there is that.
From what I understand, many men of your generation are not only choosing to not have kids, but are also choosing to stay single. My oldest nephew (now 40) was married for a few years in his late 20s, but it ultimately wound up in divorce (no kids, thank goodness). He has been single for many years now, owns his own house, has a good job and a nice vehicle. He is also making extra payments on his mortgage and will probably have the house paid off in ten years. He seems perfectly content being single. He has a group of friends (most married, with kids) that he spends time with every other week or so, gaming, watching sports, etc.
My other nephew (now 39), on the other hand, is happily married, with three great boys. The oldest just started college.
This movie clip reminds me of my oldest nephew:
Then again, I sometimes worry about the future of western civilization if too many of the, um, brighter, people choose not to have kids.....
