Well, there is something in between putting that you stutter in your profile and just showing up at a date without ever telling the other person, yes? You'd normally have some back and forth with someone before you meet, so I'd think that'd be the most natural time to let someone know. You know, like if you think you have some report, then go ahead and tell them then. If they react funny, then, well, probably not someone you want to date anyway.
