I don't think it's an excuse to not having kids, but I do think generally I have yet to find an excuse to have kids. So far it doesn't interest me. But still, I do wonder whether there's a good reason for that.
I relate to your current state of mind. I wasn't sure either before I had my first child. I didn't particularly like kids, but wondered what would it be like.
Then I had my first child by accident at 33 and it was by far the best thing that ever happened to me. I'm glad I didn't wait longer to decide rationally to have kids.
I can confirm a lot of the comments in here are true, for good or bad. But most definitely an overall good experience with love and fun trumping some minor annoyances.
