I have had this feeling, too, that if I have a genuine or intimate conversation with someone that my stuttering seems to lessen. I guess the one thing is that I feel I can't really tap into that when placing an order or at work or something of that nature, so I never really saw how I could apply that transient feeling to everyday situations. Now, I try to just be myself in most situations and not worry too much about the stutter and I think that lessens the pressure to be fluent. It's easier said than done, and I still have these inherent feelings to not demonstrate the stutter but I think I'm getting better, it's a work in progress!
