Hi, it happens to me, I stutter under certain conditions or people. I assume when I’m nervous, afraid or excited to tell something, for example my father was always judging if I was stuttering or not so I was always nervous when talking too him and probably doing it more. Also happens to me when I want to tell a joke, I believe it’s the thrill of saying the punchline in the right way. I personally didn’t overcome it but know I care less about the others’ opinions so maybe I’m doing it less, but I’m not even keeping track of it.
