beginner question
my current size is 6.5X4.5
I recieved my Vacutech system 2X9 and a 1 3/4X10 length master.
I pump for about 10-15 min 2-4 sets using 4-5.5 of pressure. I can only reach 7 inches in the tube, and this only after repeatedly lowering the preasure to about 3 and flex my pc muscle then raising the the pressure back to around 4-5.
Considering my starting size, should I pump longer time ,or more sets, or get a smaller tube that fits me better. maybe a 1 1/2 X 10 length master tube.
Any advice is greatly appreciated,
