Measuring Curvature

The measurement of erect girth and length and even the flaccid equivalents are relatively easy in comparison to the measurement of the angle of curvature of a penis.

Diagram 1

By curvature of the penis, we mean an actual deviation within the shaft, a bend occurring above the base. We are not referring to the angle of an erection, or whether an erection points more to one side than another with associated rotation of the shaft. Both of these are related to the ligaments supporting the penis and not to a curve in the shaft itself. Of course it is quite possible for a man to have both a low erection angle which errs to the left with some rotation and actual curvature within the shaft.

Extremely pronounced curves can be caused by Peyronie's disease. This is a serious condition and not one that lends itself to the rigours of PE. Milder curves have reportedly been corrected using various methods but the process of correction seems if anything harder than normal gains.

Statistically, most penises are not totally straight. In most cases of curvature, the curvature is not a gentle curve along the complete shaft but rather in a limited zone of the shaft and this should be obvious as separable from the effects of the ligaments on the base. Though curved penises are often referred to as banana shaped, a banana does tend to have a smooth curve.

The easiest way to measure a curve is with a photograph, ruler and protractor. This two dimensional image allows for separation of axes of curvature into a vertical component and a horizontal component. If the penis is curved up or down, a photo from the side is required. If the penis is curved to the left or right, a photo from the top is needed. With a curve in two planes both side and top photos are needed.

This example of how to measure a curve, uses just a single plane. With two planes of curve, the process must be repeated using the second photograph. The resultant measurement is an angle in degrees.

Diagram 2

1. Using the picture, take a ruler and draw a line perpendicular to the shaft well above the curve. Draw another line in the same manner well under the curve, as shown in diagram 1.
2. With a ruler measure the midpoint of the shaft across both marked lines, add another midpoint measurement near the base and another just below the glans if possible.
3. Draw two straight lines through the midpoints previously marked, continuing the lines well beyond the meeting point to allow easy measurement of the angle. The photo should now look like diagram 2
4. Finally, take a protractor and measure the angle representing the variation from the straight line from the base, between the two lines. In this example the measurement is 30º.

After all this, it might be questionable as to whether it is worth taking this measurement. As with all things PE related, this is a matter of measuring progress. Without good measurements, progress can't be measured and the efficacy of straightening methods or the effect of general PE on a curve remains unknown.

It should be noted that this measurement is highly variable dependent on the quality of the erection and as such, it is quite possible for a beginning PEer to assume that a curve is being massively increased by PE, when simply the quality of erections has improved.
