I think that this insecurity and awkwardness towards the opposite sex in general are unfortunate and unfavorable byproducts of modern civilization.
I think you're on to something. Any way you could elaborate on how that came to be?
I will try my best.
The way I see it is that society has unequivocally changed. Modern society is indisputably sophisticated and the technological advancements, the revolutionization of the means of production and the scientific leaps humanity made in the last ~300 years had a profound influence on the formation and workings of societies and civilizations. For the first time in history almost every individual on this planet has access to the entire intellectual and scientific legacy of mankind and can be exposed to any thought or norm that is in existence. What I'm trying to demonstrate here is that society is now so sophisticated and with sophistication comes inevitable complexity and convolution. For the vast majority of human civilization, the relationship between man and woman was so simplistic and straightforward; it was mostly an extension of physiology, survivalist incentives and clear social and economic advantages. Then came the last 200 years broadly speaking and the last 40-50 years more specifically and turned everything upside down, sometimes for the better but more often for the worse. The unprecedented abundance in affluence and material means and the sophistication and accessibility of luxuries and pleasures made people indolent and intemperate. The unprecedented liberties and the proliferation of ideologies made people lose their way. What was once solid melted into thin air and people are left without a clue on how to live an examined, spiritually satisfying and personal life. Why settle for one partner when you can have as many as you want? Why be faithful to someone with all these temptations within your reach? Why practice temperance when you can afford to eat as much as you want? If everything is tolerated and if you can go away with most moral depravities, why abstain from anything at all? As a result, virtue has been lost and what was once a simple truth became subject to all manners of twisting and turnarounds. We are riddled with insecurities and distrust of one another, we no longer stand on solid ground.
If you think about it, we're confused about and bewildered by pretty much everything relating to our personal lives and to being an individual among fellow humans.
