Depending on the type of jewellery, you may have to buy special opening pliers. Once you get the hang of them, opening is easy. I wear a banana bar (cbb) for sex. It fits snugly to the pen1s, provides more urethral stimulation than a CBR and won't move around 2 much. Check my gallery. No hole closes in minutes.
