Just asking, please

So I recalled a conversation I had with my older cousins (they are both in uni) and they say that we don't really have the urge to go get married, fuck, have kids, etc right now because we are still developing. (Note : I was 12 or 14, idr) And since we don't get that drive yet. (You know how some women or men just get this large desire of wanting to have a baby)

So I just have to ask if any of you actually decided that you are indeed (let's just say) asexual because you just decided that you don't want to have sex nor you are interested in it and yet, you never had experienced that hormon thing ever in your life and you are underage.

To all of you who are already in your 40's (idk but some article about pregnancy said that around the age 30 (i think) is where you will normally feel the baby drive) and are indeed asexuals, please do tell that have you ever feel that drive or you did but its very low type of drive?

I do sincerely apologise if I hurt anyone's feelings. I just need to know and google isn't helping. ┗( T﹏T )┛
