I've been with my partner for over 4 years now and it's never been a problem for him, in fact he gets mad at me when he senses that I'm frustrated because of my stuttering, because as he always says, I shouldn't worry about it at all, let people think what they want. Sometimes we make stupid jokes about it, like last week I stuttered one word over and over again (which doesn't usually happen to me) and I said something stupid like "damn, I'm remixing right now" and we just laughed about it. I don't stutter all the time, it depends on how stressed I am.
