This is my first post. I have experience with manual PE and using a traction device. I am looking to this forum for help on a very frustrating, reoccurring injury. I started using a traction device in the summer of 2007 (after failed attempts with manual PE) and by the end of October 2007 had logged about 400 hours. Soon after I started to notice pain in the left side of my penis and testicle. The pain was internal and a could be described dull throb which sometimes I could feel in my leg and lower stomach area. I went to see my doctor and she referred me to a urologist. After an ultrasound and inspection I was told they could not find anything wrong. After several weeks of rest the pain went away (and was only slightly noticeable after hard sex or masturbation). After about 3 months I started with the device again, and the pain has returned. It’s always on the left side, mostly in the penis shaft and left testicle (the pain seems to move around from penis to testicle). There is no bruising, dis-coloration, sores, or any noticeable problem. I have no problem with urination, sex and masturbation (Although it may be sore afterwards). As you can guess I am very frustrated. I want to continue PE, but am afraid of further injury. Has anybody experienced a similar problem? Is there a solution or am I doomed to never do PE again? Any suggestions or similar encounters would greatly help.
