My hard-on is oval. Two inches wide, an inch and a half in the other (side) dimension. I don't have a big corpus spongiosum like Pecker and others. There's a guy on here goes by bull something who has a huge corpus spongiosum. (The corpus spongiosum surrounds the urethra and makes up the glans and your penis bulb down there below your scrotum when you're hard.)
It seems like more people would have oval erections because there are two erectile chambers side by side in the body of the penis, the corpora cavernosa (plural). But, I've seen more rounder hard-ons than oval hard-ons, probably because the third chamber, the aforementioned corpus spongiosum rounds it out in most men.
The variations in size of these three erectile chambers make all the variations in penis sizes and shapes. |
