Slank: It's not too common. My guess is roughly 5 percent of men get them, maybe a tad more or less.
Yeap, the only ADS that would probably help in this regard is PE weights, as it pulls your penis downwards (and thus pulls on your ligaments).
i measured yesterday my BPEL at about 80% erection and i measured the same. so at 100% i maybe gained .1 BPEL which i was kind of disapponted in because my BPFSL is .5 in longer than my BPEL. and according to your theory this suggests that ive stretched out the tunica and i need to focus on good jelqing to let the smooth muscle tissue catch up correct?
As far as erection is concerned after the lig pop my quality went down for about 1-2 days and now it sems to be recovering.
Luckily in my line of work we have the ability to debunk through dissection... Lig pops are not from the ligament body themselves, actually the "pop" you are hearing is cartilage attached to the penis body, housed at the pubic symphysis.
OK, you've made me curious. What is your line of work?
And... could you elaborate on your statement please? If, the popping is coming from the cartilage, what is happening to the cartilage that makes it "pop?" Is is tearing? Shifting positions? Detaching? Please explain.
