For more info on asexuality, you can start with AVEN : www.asexuality.org/home/
Also, I HIGHLY recommend this book; it's absolutely the best description of what it's like to be asexual and how you can understand us: www.barnesandnoble.com/w/the-invisible-orientation-julie-sondra-decker/1118232835?ean=9781631440021
Also this delightful website of posts "I should have realized I was asexual when..." gives some great insight into the way we see the world: aceboned.tumblr.com/
And finally, this blog has aggregated a bunch of other ace blogs to peruse, though I can't speak to the accuracy of them all: asexual-literature.tumblr.com/other-blogs
Happy research!
