I was thinking.. During this period I've began to attach lower and lower attachment so one could say I'm doing expressive stretching now. So that could maybe be my "new" routine? And also, I often experience that the attachment slowly are slipping down the shaft (closer to the head) during the session. Do you also experience this and do you do anything about it? In that way you are kind of getting both expressive and more of a shaft stretch during same session...
You are not attaching the length master tight enough. There shouldn't be any slippage at all.
