8g Curved Barbell

I tried a 8g (3mm) 19mm long curved barbell today, it fitted fine but as I have my foreskin in tact it seems I can’t wear a barbell.  The bottom bead means the my foreskin wont roll back into its natural position rendering it rather uncomfortable.  So it looks like I’ll be sticking with rings only.  A bit of a shame as i would like to have had the option.  Never mind.
