I don't stutter when I read

I don't stutter when I read Hello there, for some time now, I've noticed that when I read out loud (either to myself or to other people) I don't stutter AT ALL in my native language (spanish), although I do stutter sometimes when reading in English. Being a heavy stutterer I ask here, does something similar happen to you? I've got to admit though, when I started seeing my friends' reactions of me not stuttering, I peaked.
