I identify three primary pillars of the "sexual revolution."
Antibiotics, Gender demographic changes caused by World War II, and the invention of the birth control pill.
But yes, antibiotics are what keep Homosexuals alive. There is a reason why the Homosexual population and behavior has surged since the 1960s.
Don’t know how old you are. I can tell you the invention of panty hose played a big part in the sexual revolution. Eliminated all the armor of younger women’s undergarment. Easier to give in to the passion of the moment. Readily available women’s birth control followed shortly there after. Reflected in the huge change in women’s fashion, mini skirts etc. Good times good times...
