I wouldn't hesitate to indicate that you stutter on your profile. I get that people can be at many different levels of severity with their stutter, but I don't think I would ever equate it to being as bad as any level of autism or not having legs. If someone checks out your profile online and decides against talking to you solely because they see that you stutter, it's their loss. Get out there on dates and stutter your way into their hearts. Once they see that you have the courage/balls/ovaries to not be shy about something as potentially embarrassing and demoralizing as a stutter (of any level of severity), they'll start seeing you for who you are. And if they don't? Again: it's their loss. Move on, go home, rub/schlick one out and work on setting up another date for tomorrow.
