Is it abnormal not to have a kid at 25?

I feel everyone around me has kids ages 18-25 and I just turned 25 and still don't have any kids even though I've had many close calls with ex girlfriends. I guess I should b thankful right? I feel like im done partying and ready for a kid, guess I just havent found the right girl. I know this sounds weird but I kinda regret not having a kid with my ex even though i know it would be heartache and a terrible decision, I also feel I'd fit more into society and b like everyone else and start the next chapter in life. I don't know I look at my friends and they don't have kids and I just feel like some of them r losers and not grown up and I feel like a kid would also separate me from that. Your thoughts on this please??
