Found this article on medium while scrolling through some comments in a post here. I recommend you go read the article, it's very insightful.
It basically talks about how some cis people are likely Agender due to their lack of an internal sense of gender, or them not ever thinking about gender.
I know that this isn't the only experience of being Agender. Agender experiences can be quite varied and different, and not all Agenders will relate to not experiencing or understanding gender, for some it's just a different feeling of gender, or a different type of feeling.

I do know that a lot of Agender people do though which is why I decided to post this here since I feel it could maybe help some people, or maybe just be an interesting article for people to read

Anyway what are your thoughts on this idea? If you have any thoughts or anything you'd like to add please share in the comments.
