I'll keep it short - I'm getting back into dating at 37. Focus on being there with the person. People that are dating want to meet and get to know people. They want you to be present, there with them. Focus on them, the experience and the interaction. Don't focus on anything else, including stuttering. Let yourself stutter. If she knew before hand and interested in seeing you again - it's probably not any issue at all. If you can 'forget' about stuttering (I know.. I know... we all know..) you might be surprised at how it goes.
