The Hamadryas baboon, for instance, a native of the Horn of Africa, has an erect penis that is five and half inches long — slightly shorter than an average human male, but they weigh only a third of our weight. Dixson, Primate Sexuality The human penis is in fact extremely dull — it does not have lumps, ridges, flanges, kinks or any other exciting feature that other primates have. But for others, testicles are a "hands-off" area. Testicles AKA balls are your body's sperm factory. Primates with simpler penises tend to be monogamous like cotton top tamarins a or polygynous like gorillas g. Testicles are pretty fragile.

About half of all penises in the US are circumcised, and half are uncircumcised still have foreskin — so both types are common.
