Why does it bother you so much if people accidentally mistake your sexual orientation? People wrongly assume I’m straight on a regular basis (even though I didn’t do anything to give them that impression), but I just correct them and move on. If it’s an honest mistake, is it that big of a deal? You can just correct them. Most of the time, we don’t “do” anything to signal our sexual orientation unless we are hitting on someone or showing affection to a partner. People usually make (incorrect) assumptions based on stereotypes. When people do that, we can simply correct them and suggest that they ask in the future rather than assume.
