Interesting article. Stands to reason certainly from what we "know" evolutionarily about our species and others.
Size of your member is just one component. The article was pretty clear that size was trumped by height and body shape.
Women have, I think, a much more vested interested in mates. Females have a shorter window for reproduction - teenage yrs to maybe 40s -- in general, always exceptions. They produce one egg usually and only once per cycle and during a finite window during the cycle when conception can occur. The egg holds the same genetic components as the male offering but dominates in material size, nutrients etc. Women have to gestate the offsping, 40 wks give or take with human females. A tremendous burden on their bodies and lives, some lasting long after the child is born. Females, even in our modern, more equal societies, still are responsible for the lions share of the child rearing responsibility...feeding (especially if breast feeding), other care, etc. Soooo...it stands to reason females look for a whole host of markers for a mate and penis size may be one of them, but is a much smaller aspect than we as men, always thinking with our dicks, may think.
And the article referenced that...height, body shape, shoulder width, hip structure. AND of course a board full of guys focused on the title...

Interesting article, thanks for posting!!
