As I already shown in many of my posts, Eukaryote form of life (Three Layers), in with we belong, is different from Prokaryote one (Two Layers). Also, the true place of Species are essential to understand the role of Sexuality.
We may use the planets formation analogy in the following way:
So, here we explain how each interaction must work for those two feelings:
- Big to Big (B-B): Strong attraction due to two big Objects (Two Ways);
- Big to Small (B-S): Medium attraction due to only one big Object (One Way);
- Small to Small (S-S): Small or none attraction due to very low mass involved (No Way).
- Medium repulsion between any Object due to Embarrassment.
Between this two feelings there is an Equilibrium, that equilibrium works on Shame trough Natural Selection (Evolution) in a way that only Organisms with too much Entropy are wasted. One thing that is important to acknowledge is that in essence all organisms are in some degree handicapped, and the level of deficiency is strongly correlated to attractiveness, or beauty in a negative way. This is easily viewed, for instead in optics where little marge exists for error, and in some countries of Asia you have up to 80% of people with Myopia! Susan Boyle, in the Picture, suffers from Asperger syndrome proving that the prettiest is the cleanest in terms of biological Entropy. Entropy is so present, that many persons considered perfect, turn out not to be, like the well known Ricky Martin or Wentworth Miller, showing us that nothing is safe from Entropy, including sexual orientation (Not surprisingly, Species' Shame is particularly acute in this cases)! You can see more in my older posts how Consanguinity and other issues are interconnected to Sex!
However, because Shame is always present, despite Sexual dimorphism, it requires that even in the cases of Strong Attraction things had to be done in the dark to avoid Embarrassment, also with the extra advantage to species that no feeling of injustice becomes too vivid at the point that excluded Organisms don't play as expected... For Species, making Sex its own business trough Shame enforces that Organism are more operational, being worried only with terrain matters, like food and shelter, something that by itself is a good reason for Species to adopt Shame in its reproduction Scheme!
Attraction and Shame are not exclusive to Humans, despite some illuminated people that glorifies the notion that "only Humans feel", Attraction and Shame are felt in any other Animal and they worked exactly the same way with exactly the same purpose, serve its Species.
We Humans have one advantage relatively to other animals, we can solve problems inherited from nature, and instead of bury our head in the sand, saying everything is natural, everything is cool, we may admit that a more controlled process of human reproduction is needed, acknowledge for instance that biological differences are in essence an unjust form of exclusion and not something everyone has to live with just because is something "natural" or "romantic"... More than marketing and cheap propaganda, we need to address the truth and take in our hands the reproduction mechanism, where In Vitro Fertility is a possible solution, with a increasing more efficient mechanism of diagnostic when it comes to Birth Defects! We must give to the Species what it wants and in this way put it aside from our way!
More can be done, but nothing will be if we let romantics and their ethics dominate our life with their meaningless words that are nothing more than lies serving only the Species. So, no, it's not Islam or Christianity that represses Sex and promotes Shame, is not even Communism or Fascism, is Sex itself in its Protocol implemented by their Species, where words like "Pretty" and "Ugly" are part of it!
