Back to whales again! In general, cetaceans have no protruding udders like cows. Whale mammaries are two long and fairly flat organs inclined to each other at a slight angle. Their tips are not far from the umbilicus, and the average dimensions in "resting" Rorqual cows are about 7ft. by 2 ft. 6 in. by 2 1/4 in.

The largest buttocks occur in cases of steatopygy, generally associated with Hottentot, Bushman, and other African tribes.

We all know that men are supposed to worry endlessly about penis size. In popular mythology a small organ is still thought to signal a totally inadequate lover. All the best books tell us that this idea is absurd but nonetheless the notion persists.

The Kinsey group compiled data on penis size for the detailed report on sex offenders. Various classes of offenders were asked to estimate their penis length on the ventral surface from the abdomen to the tip of the penis.

Penis lengths for various groups were found to average 6.3 to 6.5 in. It was found that only one group -- "the aggressors v. minors" - reported an above-average length penis (around 6.75 in.).

In the Dr. Jacobus survey definite penis size differences on a basis of race were detected. The largest Arab penises were found to be between eight and ten inches; but it was among the Muslim Sudanese that Jacobus found "the most developed phallus" - notably "one of the maximum dimensions, being nearly 12 in. in length, by a diameter of 2- in."

The hardy researcher remarked that this was "a terrific machine" - "more likely the penis of a donkey than of a man." He concluded that the "Sudanese Negro possesses the largest genital

Testicles are much of muchness, varying in dimensions very little from man to man. One authority, T. H. Van de Velde in his "Ideal Marriage", puts the "mature testicle" at from 4 to 4½ cm. long, and from 2 to 2⁴/₅ cm. broad.

There are sex books and sex books! There is all the difference between a piece of cheap nineteenth-century pornography and a detailed research publication in sexology. Prudes have often failed to make a distinction, and when a distinction has been attempted it has often been bogus. The biggest sex book collections in the world contain all types of sexual literature - from the simply titillating to the driest scholarly tome. The leading sex institutes associated with the names of Bloch, Hirschfeld, etc. - all had associated libraries. The Kinsey Institute
