Why are there ranges for length of penile implants and not for girth? Everyone is different and just like some men are longer there are some men that have more girth then others. We are being treated in a one size fits all mentality and it’s bull shit. These implants should be custom and even take into consideration of a tapered penis. I think men would be more likely to feel aroused if these implants were closer to our natural penis shapes and out also simulate the sensation of a erection if they properly if filled out the spaces of our penises.

How do you get that there isn't a selection of varying widths?

The following MAXIMUM diameters are available:

AMS CXR 14.5 mm (0.57") max, 9.5 mm (0.37") min
Coloplast Titan Narrow 17 mm (0.67") max, 11-12 mm (0.43") min
AMS CX & LGX 18 mm (0.71") max, 12 mm (0.47") min
Coloplast Titan 22 mm (0.87") max, 14-16 mm (0.55") min

This means that cylinders can be sized anywhere from 0.37" diameter up to 0.87" diameter. Keep in mind that besides the girth of the cylinders, there are other tissues involved in the girth of the penis, including the spongiosum, tunica albuginea, facia and remaining erectile tissues if they weren't destroyed during dilation.

Did I miss something in all the threads on FT talking about what was inserted for whom and why?

Yeah but it’s still bull shit. What if your dick is 6”x6.5” and you have a short body cavity. You think a titan 20cm is going to allow you to keep your girth? It’s not. Girth does not increase linearly with length. It would also be nice to not have to pump to max in order to have the more girth. More pumps means more fluid goes to the cylinders wich means more girth but then you have those awful pointy tips jamming your glans and if you have a longer penis it hurts to go deep into a vagina. Also I like to have a not so rock hard erection while still having great girth. Maybe I’m unique but I get good blood engorgment at max inflation but I have to sacrifice tip pain and my shaft becomes to hard.

So the chart I looked at shows a 20 cm Titan has a girth of about 20mm when inflated. 20x2=40 mm for side-by-side diameter. Factor in additional tissues and it's closer to 50mm side-by-side width. With spongiosum engorgement it will be a little less than round. 40mm diameter of a circle would be 40 x pi or 125.66 mm or about 5" girth. Since the other tissues add to the girth as well, as does the spongiosum, you're getting close to 6" girth already.

I've got CX cylinders which top out at 18 mm and my girth is just at 5". By the same calculations, 18 x 2 = 36 cm and 36 x pi = 113.09 cm girth if round. Since the results of 36pi is 4.448 inches girth and I'm at 5.0 and my cylinders aren't fully inflated (still feel the pressure/pain), there is considerable additional girth in the penis besides the max 0.87" on each Titan cylinder.

I think correct sizing is imperative......I have never had pain in the tips/glans.
Choose your surgeon well

Smetro, to clarify my pressure/pain statement, I was trying to make a point that despite the calculated girth based on cylinder diameters at full inflation, that I already had more girth and I have not reached the maximum girth possible from the potential inflation diameter on my 18mm CX cylinders because at full inflation I still feel pressure/pain. Point being, there is more to girth than the sum of the cylinders and I am the proof.

I have no dispute with your conclusions but feel compelled to point out that geometrically, two 20mm circles side-by-side (as are the cross-sections of penile implants) are not equivalent in area or circumference to one single 40mm circle.

Very true but the cylinders are only a fraction of the cross-section of the penis. Other tissues, spongiosum (and urethra), tunica, facia, remaining cavernosal tissues, etc. all make up the overall circumference (although more oval after implantation). My specific girth of 5" goes to prove that. When I'm implanted with CX cylinders that have a MAX inflation of 18mm each, or 36mm when side-by-side and 36mm=1.417323". Yes, that's two side-by-side circles which isn't in itself a circle, but assume for a moment that it IS the diameter of a circle: 1.417323" times pi equals 4.4526515" in girth. I have 5" girth from two side-by-side 18mm (MAX) circles. That means the other tissues involved in the penis account for the remaining girth.

The cylinders after implantation are only a fraction of total girth. They are a good percentage of the girth (maybe around two thirds) but they're not the entire picture.

If you put a sleeve over two 18mm cylinders side-by-side, that sleeve would have to be 92.5 mm. If you put a sleeve over a single 36mm cylinder, that sleeve would be 113mm.

Of course, a man's penile tissues surrounding the implants (and including the tissue BETWEEN the two side-by-side 18mm cylinders) would increase the size.
For example, if there were 10mm of tissue BETWEEN the two 18mm cylinders in my above example, the sleeve would have to be 112.5 mm.

A lot of suppositions about tissue which varies from man-to-man, including any cavernosum tissue remaining inside the Tunica, which depends on how much the surgeon removed.
Another variable is that SOME men retain (and, rarely, regain) some cavernosum tissue erectile ability after implant. Possibly due to venous leakage mitigation through compression of the implant. But that is another speculation.
