Don’t make it your identity, but don’t be afraid to talk about it either. People like honesty and vulnerability. I’ve stuttered my entire life and have had many girlfriends. I live with my gf now and she teases me when I get nervous and order takeout on the phone and fuck up the order. You get used to it. For first dates, just be honest. If they’re a good person they won’t be a dick about it and will accept you for who you are.
