I'm about to graduate medical school and I stutter in front of patients, teachers, and peers. When I do stutter, I mention that I stutter in a confident, brief way and move on. In my estimation, that show of confidence and awareness reduces tension that others may feel as well as displaying that I am indeed confident, opposite of the stereotype that some may have. On the social level, it's part of who you are, so if potential friends or SO's judge you harshly, they're not people that you should waste your time with anyways - it can be an efficient way to eliminate people that you wouldn't want to be with after all.
