I don't stutter when talking with an accent

I don't stutter when talking with an accent I like to talk with an accent to mess with my friends and family, and I noticed that I don't stutter when talking with an accent. Like, never, maybe once or twice. When I talk normally I stutter quite heavily. Does anyone else recognise this? It's kinda funny, but also sad that I can actually talk fluently, just not when talking normally 🤨
