People always seem to suggest anything you do whether it be bodybuilding, success, status items, speeding, reckless behavior is always making up for your small penis... its really quite ridiculous 
small penis or small man syndrome is just one of the most common shortcomings in men, but it's essentially only part of a wider masculinity, virility problem in a deeply changing society where men lose everything they had and made em unique to women who are becoming more and more equal in every aspects of life.
Basically men dont know how to be men anymore, their identity and references are being destroyed on a daily basis.
Men not only have troubles knowing what it is to be a man, what is a "true" man nowadays, and all their references are being annihilated as their occupations, roles and way of life change drastically. As a result, fatherhood also changes. Men dont know how to be men and how to be fathers.
Men and women dont want kids anymore cause they want to focus on their own individual "freedom" and leisures, so they decide not to have kids or have them later in life compared to our ancestors . Also there is no more need to have several kids cause life span and quality increased tenfold.
It will take some time before there's a new unique universal and adapted model of what being a true and efficient man is in this fast changing world. A matter of decades. In the meanwhile societies will produce millions of dysfunctionnal individuals and women will see their power increase.
The macho man is clearely an endangered specie, unable to adapt.
