I have a mild-to-major stutter, depending on the day. It's never been an issue in my dating life. I've had people not notice, I've had people tell me they think it's cute, I had one person give me a mixed cd with a Magnetic Fields song with the line "you stutter like a kaleidoscope because you know too many words," I've had people tell me their flattered when I do and do not stutter around them, because they think that either one of those things is because I'm comfortable with them. I tend to only be anxious about my stutter in public speaking occasions or when talking to new people, otherwise I just barrel on. I think that has made it a non-issue. If someone isn't attracted to me because of it, they won't go out with me, and anyone who will just has to deal.
