I had really decreased my extender hours lately, due to general inconvenience and discomfort,
You are using the first vac-extender, right? What problems did you encounter? Scrotum burn from the base? I am using it for 12 hours these days and I have had problems with the scrotum burn. The way I solved that problem was by putting a baby-sock over my scrotum. Also, how do you measure the tension with the extender? I use gerrykjohnsons method of doing a BPFSL measurement. I am 18cm BPEL so I stretch to 18,5-19cm BPFSL.
