I don't want kids, ever. Is that weird?

Hey guys!

So when I was about 12/13 I decided that I don't want kids at any point in my life. I'm 17, almost 18 now and I still haven't changed my mind despite pretty much every single person who knows I don't want kids being like 'you'll change your mind someday!!!'. While I am open to the fact that one day my mind might change, it seems very unlikely to me bc I've been so sure that I don't want kids since a young age.

For years, I've constantly had to defend myself and explain why I don't want kids to so many people. Whenever I mention it people act like I've just told them I killed a puppy. It's a personal choice that I shouldn't have to explain but I constantly find myself giving reasons that result in me being called selfish or weird or whatever. My reasons are basically 1. that I don't think I could handle the responsibility, 2. the idea of getting pregnant completely freaks me out (a little alien thing growing inside me? nope, no thanks) and 3. honestly, I just don't like kids.

So what I want to know is: do any of you guys definitely not want kids? Have you experienced the look of horror on people's faces when you tell them you don't want kids? Obviously you don't have to explain yourselves but if you want to talk about it in the comments section feel free! I guess I just want to feel less alone in this bc pretty much every girl I know wants kids and I feel like a bit of an anomaly haha
