What is a common way to express genderfluidity? I know some asexual will wear a black ring on their right middle finger. Is there anything like that for genderfluid people?

There's no universal way to state you're genderfluid without actually saying it, but you can drop hints by wearing the genderfluid colors / flag on a pin or other accessories, or you can mix "stereotypical" feminine and masculine clothes. Of course, genderfluidity can also be expressed through pronoun usage.

There's many ways to express being genderfluid! You could wear some socks relating to the genderfluid flag colours, bracelets, rings, jewellery. There's so much you can do with expressing yourself, wear it with pride :)

As an Asexual person I often opt out but purple of green often represents in color so why not wear something purple or make your own symbol I myself only feel comfortable in wearing a black jacket yet I still stay true to myself because people don't quiet understand our sexualities yet we can live free lives as gender fluid people I would say make your own trust me it will make you feel better and respect yourself more then when someone else makes a symbol of representation good luck I hope you of the community makes a common way to express

i believe their gender pronouns can be a source of identification. Other times genderfluid individuals like to tell you that they are genderfluid. They like to be asked directly, but don't stereotype that with everyone or always. It's also important to give them privacy if they don't want to answer. I would simply ask them if they appear a certain way but never assume. I was not aware that asexual individuals wear a black ring. See never assume and always ask and be kind and never be assertive as it is a sensitive thing too. Thank you :) xoxo
