The UK Asexual Conference has been a yearly conference for all asexuals and allies, held to date in London. We've had an exciting range of panelists every year, with activists to talk about meet ups, organizing, and current events. We've had experts in their fields talk about the state of academic research into asexuality, to run discussions about gender, and to run "Ace 101" discussions.
All of this takes money unfortunately. If you're able and willing, please go here to donate: https://www.asexuality.org/en/topic/174042-help-us-create-more-uk-asexuality-conferences/
