Tried a 7" DIY urethral electode for the first time last night and I must say it was pretty good. Used in conjunction with an anal electrode, it felt like it was lighting up my balls, interestingly enough. However, what do you do with the "after"? Felt like I was peeing crushed glass every time I go. Each time is a little less painful and now mostly at the beginning of the stream. Is this a common consequence? I know my DIY electrode was well-rounded on the end, polished all over, and inserted slowly with lubricant. More lube? Special lube? Or this is just the way it is for a couple of days after. Medically, I have had a catheter inserted before and it wasn't painful after removal.
