So this isn’t my one to comment on, as I am not asexual, though I will hopefully have something by someone who is to share soon.
Instead, I am going to use this opportunity to link to resources that will give you much more accurate information than I can:
AVEN: the Asexuality Visibility and Education Network is one of the largest and best known resources available for Asexual and questioning individuals, or anyone who wants to know more. Highly recommended.
Demisexuality.org: a really good resource for further along the asexuality spectrum. Because yes, there are more spectrums.
Taking the Cake: for people who like more visual primers.
AAW.com: the website named for the week, they have a lot of different resources available, hard copy as well as digital.
Of course this is by no means an exhaustive list of resources, but they are all ones I’ve found useful.
