One question about hg
Guys what is the increase of 4hg , and at 5 hg I mean lenghtwise in the cilinder , for example when I enter the pump erect at 4 hg I only expand 0.5 or 0.25 cm more than my normal erection ? At 5 hg I expand between 0.5 and 0.75 cm than my normal erection ? Is that normal or I am doing something wrong ?
