It has helped me to self disclose it but in a non-apologetic way. The more you try to hide, the more it will come up. If this is a deal-breaker for the person, then they are not worth your time. Once again, it's super important to disclose it in a non-apologetic way and maybe in a joking manner. The vast majority of people find it super unattractive when people are self-deprecating, whether it be about a stutter or not. Imagine going on a date and the other person is already burdening you with their problems. We all already have enough of our own problems and insecurities. I was found of your post though. I'm very smooth and witty in the dm's but do not always bring that same energy into the date. Best of luck!
