30M When I started talking to friends and colleagues about my stammer, I was so surprised by how many of them commented on my stammer being humanising and charming. Its quite a vulnerable thing to stammer in front of people, and I think some may find it to be somewhat of an honour - 'this person trusts me enough to stammer in front of me' etc. So you can definitely play with it in that way and see how it goes. I feel like my stammer is quite mild too, so many people dont notice it at first. No one is perfectly fluent, so I might just sound like a regular person to most people I interact with. I definitely feel that I am hyperaware of my stammer, making it out to be much more worse than what is actually is, which is understandable. It is however important to note that hardly anyone else will see your stammer at the same heightened state that you do. That is quite a funny situation you have found yourself in with this dude - I would view this as an opportunity to change his world view of people who have stammers. It sounds like he isnt very well informed on what a stammer is, possibly having only heard of them through movies and the likes. Gently, but firmly assert that a stammer doesn't reflect the persons intelligence in any way. I would never go out of my way to tell anyone I have a stammer, its not part of my identity, so I would only bring it up if I found an opportunity within the conversation (like with this dude mentioning that Biden has a stammer). I used to mention that I have a stammer when filling out job applications etc too. Now I only mention it if someone asks, or I find a nice opportunity to bring it up (and I feel it would beneficial to the conversation). Good luck with dating, try to not let your stammer get in the way of this, dating should be fun and playful. You could view the stammer as a filter or sorts, those who mind dont matter, and those who matter dont mind <3
