I got pierced in late March with a 10G (gauge) Prince Albert I was hesitant to remove the ring. I only removed it once and had trouble getting the ring back in. Two months later I got stretched to an 8G at the piercing parlor. It hurt a little bit just to get it stretched. I never took that one out either for fear that it would not go back in. (the smaller the G number the larger the ring thickness) Today I removed the 8G Circular. Barbell and put in an 8G curved barbell. It went in easily and then I took it out and put the circ. barbell back in. I had been playing with myself a bit before and had some pre-cum worked up. I had a 6G ready for my next stretching. I put some vitamin E oil on it and tried to insert it. It went in the same as the 8G, no pain, no problem.
