Why do I not stutter when I stream?

Why do I not stutter when I stream? Months ago I decided to start streaming on Twitch because I wanted to share my drawing process, I noticed that I rarely stutrer, unlike talking in person when I stream I only get maybe one block every 10 sentences or more the rest of my speech is completely fine, thats so unusual for me. I keep asking myself why and how?? but I can't figure out the answer yet, this situation is not like recording yourself talking alone, I'm aware a couple of people are listening to me rn I see the viewers type in chat, but my mind doesn't mind that.
