Act like yourself, and remember that most people in adult life DGAF. Maybe even make fun of yourself a bit. Emphasize your good qualities, and understand that women can be just as shy as you. Ask a lot of questions, and LISTEN to the answers. Lots of people love to talk about themselves, and you can find out cool shit about people by asking the right questions. And understand, if they would judge you for your stutter than they werent worth dating in the first place. I met my wife on tinder, which helped because she knew something about me before we met in person for the first time, but shes the only woman I met online whom ive seriously dated.
