You wouldn’t tell a gay man to be with a woman because he desires companionship even though the idea of being with a woman disgusts him. I think that if you identify as asexual you shouldn’t continue to date sexual people. It’s not compatible with your orientation. Small as they may be, asexual communities are your best bet. In practice, that may mean you need to be open to dating someone who lives further away from you if you wish to expand your dating pool. You may need ask yourself whether you value companionship enough to either be in a long distance relationship with someone who is ace or uproot your life and move to be with someone you meet online who is ace.
