It has been shown that there is a positive correlation between height and penis length, but that does not mean every tall person has a long penis. There is no evidence that there is a relationship between the size of feet, hands, or nose to penis size.
In my opinion, reports of a positive correlation between penis size and body height really miss the point. The fact, as observed by almost everyone who has posted on this thread, is that there exist human males who simultaneously possess great body height and small penis size, and there likewise exist human males who simultaneously possess small body height and great penis size. Therefore, there
cannot be a causal relationship or 100% positive correlation between body height and penis size; the two features are determined (at least mostly) independently of each other.
I suspect that the slight positive correlation that some researchers have observed between body height and penis size is concomitant with population-level differences in the average depth of the vagina. In other words, I think it may be more likely (though not inevitable) for female members of populations in which the average body height is greater to develop deeper vaginas, which tends to cause the average penis size to evolve in the same direction so that it will be proportionate to the average vaginal depth of their female mates. However, it is clear to me that vaginal size is also determined independently of body height, because I know of some populations in which the females tend to have small vaginas (and the men tend to have correspondingly small dicks) despite their relatively great average body height. There must be some other (rather weak) evolutionary pressure that causes females to develop deeper vaginas (and their male mates to develop longer penes), and to which a population with greater average body height is
more likely to be capable of adapting.
