How do you measure erection levels

How do you measure erection levels

I read how your suppose to jelq while your around 50-70% erect? My question is how do you know how much of an erection you have? It’s easy to tell when your at 100%, but how do you know when your at 65 or 70%?

It’s an estimate. More than half-hard, not quite fully erect.

needle86, when we say 75% (or whatever) is a way to say between semi erect and fully erect. That’s all it means.


I really think we should have a better answer to the question of measuring erection levels (EL) than guestimation!

Too many posts describe routines in terms of EL, indicating for example 5%, 65%, or 95% erection, when we actually hardly can differentiate better than soft, medium and hard. Everybody knows what 100% EL is, but 0% is already confusing. It means completely flaccid, but what about turtling? We definitely need an objective reference. I challenge the engineering oriented folks to come up with ideas and eventually make a standardization on this matter.

As a starter, here are some ideas to define the EL accurately:

1) Ratio of instant volume of the blood inside the unit versus the maximum volume of blood that is accommodated at max. erection. As we cannot directly measure the trapped blood, I change the definition to ratio of instant volume of the unit versus max. volume. The volume of the unit is easier to measure, but still impractical.

2) Ratio of instant blood pressure in the CC and the maximum blood pressure in CC at maximum erection.
Blood pressure inside the CC is difficult to measure, so this definition is not very useful.

3) Hardness of the unit as ratio of instant hardness versus maximum hardness at maximum erection. This seems to me as the most affordable measurement we can have, as it is accessible and quick. There are a lot of devices used in manufacturing and research – durometers . Someone could design one specially for PE. We also could have an alternative to Mohr’s hardness scale tailored for PE (Let’s say, Dick’s scale :) )

I suggested ratios of the measured value against a previously measured maximum value to have actually percents from 0 to 100 for everyone. It is not necessary to be like that, absolute units are fine too and we could compare EL-s of different individuals. I’d like to hear your pertinent opinion.

P.S. As I was posting this, I found a very good early contribution of ModestoMan Alternative measure of erection level

Starting BPEL: 6.9" (Dec.1st, 2008)

Current BPEL: 8.11" NBPEL: 7.63" BPFSL: 9.09"
