Hi everyone one this will be my first post in a long, long while. For the most part I’ve been a silent observer, but measuring volume popped into my mind as well, so I was glad to see a discussion already going and couldn’t resist but to weigh in as well. :)
Remek made this point already, but just to reiterate, if you’re only taking linear measurements to measure progress you are missing out on the full picture because volume does not scales linearly. But why do we care about volume?. We care because volume is the physical meat you’re adding to your member and I think is really what is perceived with “size”.
To use an example similar to remek, take two guys:
“Average-ish Guy”: Length: 5.75” Girth: 4”
“Big-ish Guy”: Length: 7.25” Girth: 5.125”.
The big guys linear dimensions are only about 25% bigger than “average guy” and on paper they don’t seem that drastically different, but if you were to see them in person I think girls and guys would agree the big guy in comparison looks massive — like twice the size massive — and if you do the volume calc you’ll see that in fact he is. So I think there are two main takeaways:
Firstly when it comes to TRACKING progress you’re selling yourself short (yes pun intended hehe XD ) because where you might only measure a 10% increase in length+girth, that’s really ~30% more meat you just packed on. That’s huge! Think about how buff (or fat) you’d look after adding 30% to your body weight :)
Secondly (which is where I am most interested) volume can play an important role in MEASURING progress. Since volume changes more rapidly than linear dimensions you’ll detect change easier, and I think volume can also be measured more accurately and would be harder to fudge.
So now the question is how, and I think goonbaby framed the problem perfectly:

Any thoughts?
Why yes, goonbaby. I have a thought :)
So actually I think I’ve got something that works quite well and meets those requirements quite elegantly. The method:
1. Take a plastic water bottle (Dasani worked perfect for me), and cut off the top. The top is tapered so cut it just far enough down that you fit in without catching the edges.
2. Fill the bottle to the top and weigh with a scale. Ideally the scale should be accurate to the gram. (you can pick one up for ~$10).
3. Get hard AF.
4. Cram it into the bottle. (I’d be standing in the bath tub at this point)
5. Measure the weight of the remaining water.
6. Subtract the two measurements measured in grams, and multiply by 0.061 for in^3. Equation: ([Weight Full] - [Weight Remaining]) * .061 = Volume (in^3)
So its a pretty cheap/easy/one size fits all sort of approach. And if you can’t fit in the water bottle or its not long enough, you’re done.. No more PE required ;)
A few Notes:
- Try not to tip the bottle too much until you are all the way in and you have it pressed up against your pelvic area. At this point you have a pretty good seal and you can tip it a bit more horizontal.
- The custom sized opening is nice because you can press it to your pubic bone and not get fat or ball sack in the bottle.
- You only need to take the full weight once (in step 2) as this won’t change from week to week if you are using the same bottle.
- If you don’t have a scale, you can run through steps 1-6 then set the bottle on the counter and a ruler up next to it. Have the 0 end on the counter. Record the height of the bottle (this only needs to be done once) and then the height of the remaining water level. Take the difference of the two and that’s your “normalized” volume measurement expressed in inches. It is meaningless in absolute terms, but its meaningful to you as long as you record your start point. This linear length will then change in direct proportion to volume so should be more sensitive than length/girth measurements and again will be harder to fudge. — if this is a bit too abstract then just drop the $10 on the scale ;)
Anyways these were just my thoughts on this. I’ve been an on and off PE’er for the last ~7 years (actually ~14 years if you count gripping your dick super hard and vigorously rubbing as PE. Because if so I’ve been on that routine daily :D ) but I just ordered a pump which I am excited to give a try; this will be my first time. My hope is a bunch of unlocked new gains which I’ll try to measure/track with the volume approach outlined above.
And on one final note since I saw this pop up throughout this thread lol, for anyone wondering about “the cul de sac”, its referring to the “Rectouterine pouch”. In sex terms this would be the “a-spot”, which is basically another “g-spot” all the way at the back. You need to go balls deep with a pretty long dick to hit it and it doesn’t work for every girl, but if you have the dick and you have the girl, it can be some of the best sex of your life.
