Shape
The analysis of shape in the Kinsey census sample showed that,
when viewed from above, about 87% of erections were straight and
the remaining ones were curved to the sidewith more than 4
times as many curved to the left as to the right (see Table 3).
The comparable figures from the photo sample offered confirmation
of the larger, self-reported data set. Kinsey's side view
data indicated that about 25% of erections were u-curved (curved
up) and about 70% were straight. These figures received partial
confirmation from similar but slightly lower values in the photo
sample. But, whereas only about 5% of the Kinsey subjects
self-reported their erection to be of the n-curve (curved down)
shape, nearly 15% were identified through the questionnaire-photo
data collection techniques of the present study.
