Just curious as to what the various shapes of fellow lpsgers are, I'm n-curved with a slight curve to the left. I've seen an older cousins dick hard when I was younger and was fascinated by the shape of his penis, he was u-curved and it was shaped like a banana. Being naive at the time I hadn't seen a penis like his before. What shape are you? Feel free to post your experience. 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 sideâwith more than 4 times as many curved to the left as to the right. Kinsey's side view data indicated that about 25% of erections were u-curved (curved up) and about 70% were straight. 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.
