Anyone else’s stutter is like this?

Anyone else’s stutter is like this? Im 21, started stuttering in 4th grade. My dad, uncle, grandma, and some cousins stutter so its def genetic. I only stutter on words with multiple syllables especially if the accent is on the second/third/anything other than the first syllable. I have no problem with words where the accent is on the first syllable. Anyone else??
