Been a while but if Hinge has the prompts still I would look for one that you can turn into a joke about it. Like if it’s food say you love fast food drive through but you’ll have to order because I stutter. Or two truths and a lie was a popular one, throw your stutter as one of the truths. If it’s a different app perhaps put it in your bio in a funny way. You can also say you’re a really good listener since you prefer to listen more than talking.
