I used tinder before. I'd always disclose my stutter on Day 1 of talking. Most didn't care. Met one girl on there who didn't care, we connected on 'The Office' Been together 6 years now, married for 2. Just do it. I always disclosed my stutter because why not! If they don't want to be with you because of a stutter, then you're better off knowing that sooner than later. I almost guarantee you though not many people care.
