Loss of tugback is the angle at which your stretched penis no longer pulls back when kegeling. When flaccid, grasp behind the head and stretch out applying mild tension. Begin by stretching up toward your chest. Kegel. You’ll feel your penis retract against your pull. Lower the stretching angle gradually, lowering toward straight out, and then below. Repeat the kegels at each stage. At some point your penis will no longer retract. The angle at which the retraction stops is your LOT. Loss of tugback.
The theory (see KOG’s presentation) is interesting. I experienced some effects corresponding with it. However, I doubt it is an all-encompassing explanation of what happens for everyone who PE’s. I’ve received some PM’s from a few guys who had no tugback in any position, even though they were apparently checking correctly. How do you explain that? I can’t.
At this time I’m not sure what relevance LOT theory has. Based on my experience and observations, which may or may not be atypical, I don’t dismiss the theory out of hand. Some have been inspired to dump it, most likely because Bib sullied his previously stellar reputation here by abandoning Thunder’s Place to plant new stakes in dark, ugly commercial PE pastures rich in manure. While that move greatly diminished my opinion of him and his alleged values, his LOT theory is still interesting. I don’t know where it fits in the scheme of things. At the very least it got the PE community to thinking about lig gains and shaft gains being distinctly separate things. For that alone Bib deserves credit.
My current opinion and advice is to focus on stretching/hanging at the lower angles at first regardless of your LOT. Get whatever you can out of stretching ligs, because those are the easiest gains for most. Then switch to a focus on lengthening the shaft itself.
Monitor your LOT over time. Why not? It’s quick to check once you know how. See if it changes. If it does, see if the changes match with the theory. Report back. Is the myth busted, plausible or confirmed? Without more data we won’t know.
