Petitfaun, thanks for the info. My tube is not tapered though.
I pump at 6hg 3 x 15 minutes, kegelling and Jelq in between. I do not get a donut.
I did try 7hg for 3 x 10 minute sets but got a few red spots from burst capillaries so don’t go above 6hg now.
I am not sure what you mean by rapid pumping but I go into the tube erect and then pump up to 5hg fairly quickly (a few seconds) because I lose my erection quickly without stimulation, then get up to 6hg.
I will try opening my legs while pumping to see if it pulls on the ligaments more.
Avocet, when I used to manually stretch whilst flaccid I would stretch somewhere between straight out and straight down, this would cause soreness in the ligaments which I took to be a good thing. It was not a pain though.
Now you mention it, erections are not meant to go in that direction and it does seem like not such a good idea for me to pump with the tube hanging downwards and it could lower my already unimpressive erection angle.
Hog6.5, interesting you should think that vertical pumping would hit the ligs harder. I would have thought the opposite to be true.
If you think it hits the ligs harder wouldn’t you be longer in the tube instead of 1/2” shorter?
Will be interested to read your future report.
