There are handsome studly aboriginal men, but few and far in between. And statistically not all are hung.
Its the same with dark skinned men in the USA, but their percentage of the total population is much higher.
~ 5 times higher.
So for every stud you will come across ~ 5 or so not so studly guys.
When the population percentage increases this helps the likelihood of meating one..
Our indigenous population is not as madly religious as the African dark skinned guys. Also the aborigines are more likely to go for a dalliance than the highly religious African married dudes. Variations on individuals being considered.
Also most of our population of women (compared with US women) are not into interracial. Some are but very few. I think there is a multitude of reasons, but religion may be one.
This of course is my opinion.
