First and foremost, asexual awareness is all about visibility. Being a relatively new community, asexuals rely heavily on word of mouth. Telling your friends about this blog would be of great help. If you would like to go the extra mile and put up a few fliers around campus, I would be more than happy to email you the fliers that I created.
There are also some other symbols associated with asexuality, which you can use to show your support for the asexual community.
The asexual flag was adopted in August 2010 and has since been used in a number of areas and events such as Pride parades to help bring greater visibility to the asexual community. The black stripe is representative of asexuality, the gray stripe is for gray and demi-sexuals, the white is representative of sexuality, and the purple stripe is representative of community.
This symbolizes the notion of "cake is better than sex" and also the general feel-good and welcoming notion that is attached to cake.
The asexual community frequently use the Ace of Hearts and Ace of Spades (playing cards), a play on words ("Ace" is frequently used as shorthand for asexual). There is no preference for one or the other, but unofficially, the Ace of Hearts can represent asexuals with a romantic orientation and the Ace of Spades can represent asexuals that identify as aromantic.
