I accidentally learned about this orientation on the Internet, I saw a deviantART profile of an asexual person. So I started reading about it and I found out it matches me. This was a great day :) I was very happy that I learned something new about myself. A few horus later I made a symbolic drawing with ace dragon (I love these creatures).
I wasn't interested in physical relationships around the time my friends were starting to develop those feelings (I would have crushes, but they were purely romantic and not sexual), but back then I concluded that I was just going through puberty slower than they were. Late to "bloom", so to speak.
But by the time I was eighteen and only months away from starting university, I first found out that asexuality was a thing and thought to myself, "oh... that makes a lot more sense!" I just thought my hormones were taking their sweet time to kick in.
When I was 20 or 21 (something like that) I think I might have had my first (and so far, only) sexual attraction, and noticed it was towards someone I had already grown close to. That made me question whether I was asexual and this was just a random exception (you know, how a lot of heterosexual people have one or two homosexual attractions perhaps in their lifetime), or maybe my hormones really had just been late to kick in after all!
But like I said, I don't think I've had any sexual attractions other than the one, and even then I'm not completely certain that was a sexual attraction! I'm mostly just confused by it all and okay with being confused.
I tend to identify as "almost asexual" or "asexual-ish", meaning I'm more likely demisexual (or possibly grey-asexual, but demi makes sense based on how that one off attraction happened).
So yeah. Here I am now, content with recognising myself as ace-ish ever since!
I actually discovered it because of a fan fiction and then I looked it up on the internet and suddenly I had that 'Ah Ha' moment and was so relieved to know there were people out there like me :)
Nice to know I'm not alone. :D
