It was never a really problem for any of the people I dated. With my current S.O though, I was upfront about it and mentioned it myself. We met online so I felt pressured to 'reveal' it before it came up on our first call. She doesn't mind it at all, if anything she likes it. Like others have said, we tend to care about it a lot more than they do. My only tip is to bring it up if something they say or do bothers you. We lived with it for so long, they haven't. Some people haven't met anyone that stutters before. Good luck.
