Stretching my Ears: No Trouble until the 8g to 6g stretch?

My right ear did the exact same thing yours is. My left ear stretched up fine but my right ear just wouldn't go. I know for me, I had a build up of scar tissue on my right ear that prevented the taper from sliding in past a certain point. I recommend massaging your ear with something like Bio Oil or Vitamin E oil twice a day for about a week. If anything, it'll make the skin more pliable and loose to work with. I'd also say to try tapering in the shower. The steam always seems to help things work more smoothly. Whatever you do, please don't just shove it in. I tore my ear trying by doing that and it was one of the most painful things I've ever experienced.
