I think when you meet right person, it’s ok to share that you are anxious and it’s ok to be yourself. If the relationship is right and the person is a good match, it’s ok to be vulnerable and you don’t need to be perfect. Unless you anticipate to do something extraordinarily bizarre, you can’t really scare the right person by being yourself. Ultimately you can only be yourself. Eventually true nature comes out anyways so no point to be anything less than yourself from the get go. For all you know he might be anxious too!
