How a 5% girth gain can make a "big" difference

123

Hmm - I was just going to figure out my SA using the formula, and noticed the formula uses radius rather than circumference. That doesn’t work for me since my penis is wider than it is flat. Is there a way to convert the formula so it uses circumference?


*I measure PRE-WORKOUT, normal erection* Started: 7 EBP x 4.9 EG. Several years on and off PE, now 8.125 EBP length x 5.5 EG midshaft (5.8 base). Working on girth (clamping) again after breaks due to injuries - fast recent gains! Pics

(I meant, my penis is more an oval shape in cross section than a perfect circle, so radius doesn’t work for me)

Surface area can be measured by integrating your girth(length) from base to end. To make it not too complicated use basegirth(length=0), midgirth(length=0.5*bpel), belowglansgirth(length=bpel-glanslength) and maxgirthglans. I’m using a cone approximation for the glans.

The surface area becomes the sum of:
(basegirth + 0.5*(midgirth-basegirth))*0.5*bpel +
(midgirth + 0.5*(belowglansgirthgirth-midgirth))*(0.5*bpel-glanslength)+
maxgirthglans*0.5*(glanslength)

my formula DOES use circumference

In Part 1, I teach you how to calculate your diameter (radius is half the diameter). Circumference is the same thing as girth.

In Part 2, I use the radius I calculated in Part 1 and apply it to the formula.

PART 1

C = pi X d
4.2 = 3.14 X d
4.2/3.14 = d
1.34 = d (my diameter was 1.34)

PART 2

SA = 2 X pi X radius X length
SA = 2 X 3.14 X 0.67 X 5.25
SA = 22.09 square inches

PART 3

V = pi X (r X r) X length
V = 3.14 X (0.67 X 0.67) X 5.25
V = 3.14 X 0.45 X 5.25
V = 7.42 cubic inches

Viola!

You guys are making it way more complicated than it has to be. Imagine a rectangular sheet of paper L long by G across. If you roll it into a tube, you have a cylinder L long with girth G. The area of the rectangle is L x G and the area is preserved when you roll it up.

So the area of the cylinder is Girth x Length.

From that you can see that girth and length affect surface area directly and equally. If you one by 10%, the surface area increases by 10% too.

However I don’t think surface area has anything to do with perception of size. Surface area doesn’t make much sense in three dimensions. Put two pieces of paper together and the surface area barely changes at all, but there’s twice as much paper there! A crinkled surface could theoretically have infinite surface area. What will give the impression of size is displacement, ie volume.

edit:

If you want to use several girth measurements, it’s Average Girth x Length.

But when finding the average, remember that ones in the middle count twice, eg: for Midshaft, Behind Glans, and Base girth:

average girth = ¼(Base + (2 x Midshaft) + Glans)

Olaf: this sounds logical to me. Again, I’m a lit. major, so I haven’t a clue. But displacement sounds correct; what we’re looking for is the measure of the degree to which the vaginal walls are pushed out.

trust me…

stick to the SA and V forumlae I used above…I think they are the easiest and most accurate ways to calculate the growth of your penis…the most important, in my opinion, is VOLUME
