Thanks for the kind words, everyone - and good luck to everyone that’s starting as well!
I took some of the advise and did change my routine a bit - 10x 30 sec stretches followed by ~100 jelqs, or until I start to feel a bit fatigued.
However I think I will be taking a minimum few days off PE. While I was jelqing today, I felt a pinching feeling about halfway on my shaft - I figured I had just pinched a bit of skin as it really didn’t hurt, until I changed my grip and felt another pinch in the same spot. This was after a warm up, stretches, and about 15 jelqs. I did feel a vein on that side of the shaft somewhat rigid compared to my others, even while flaccid. So at this point I hope I stopped early enough and don’t have a thrombosed vein.
I suppose I must’ve been gripping too hard, or my switch to a counted vs. Timed jelqing session actually put my dick under a bit too much stress. I don’t believe I grip too hard when jelqing, but after this goes away I’ll be back to it with lower intensity and a lower number of jelqs.
Kind of sucks that I have to stop for now, but safety first I guess. Luckily there’s no pain so I’m not too worried about it.
