I like another member thought it would take forever to graduate to a 5 inch leather ball stretcher. I have been able to wear it comfortably for a couple of months for 5-7 hrs/day. My question is this -- there is a recoil action when removing the stretcher so there is not 5 inches obviously between body and balls when it is removed. I am not disappointed by that since the stretching has accomplished enlargement of my balls, firming and becoming more perfectly spheroidal. I do wonder if eventually there is no further use in using this size stretcher. So how long for as permanent effect as is possible with these devices.
