I feel like I'm the odd one out here. I don't disclose. Then again, though I do have a noticeable stutter, in no way do I think it defines me. Sure, I repeat a few words a few times. I have blocks. I have stops. But none of them impact my speech so much that I feel the need to disclose. It usually gets brought up during the date. Either by me saying "sorry, I have a speech thing" (one of the few things I can say fluently) or the person asking "Do you have a bit of a stutter?" And then it's addressed. But if I feel the need to say it beforehand, prepare someone for it, that makes me feel like I should be ashamed or feel like I'm inconveniencing someone. And I don't think either of those things.
