I posted the other day in the beginner section but i'm not really a beginner. I've only been doing jelqing for a few weeks but my dick is pretty damn resistent to injury so i've been doing more than just a few minutes of jelqing at a time. Often I wet jelq for 30 minutes at a time. After that, i'm not even sore. I apply a good amount of pressure but no matter how much pressure i use it dosen't really hurt.
My flacid length is better but my erect length isn't yet...
So I usually warm up for like 7 minutes with a hot towel and then stretch for 15 minutes and then wet jelq for (up to) 30.
Anyway, is 30 minutes too much?
Also, can I clamp with a shoe string?
