What marks the modern sexual revolution out as distinctive is the way it has normalized these and other sexual phenomena. It is not therefore the fact that modern people look at sexually explicit material while earlier generations did not that constitutes the revolutionary nature of our times. It is that the use of pornography no longer carries the connotations of shame and social stigma it once did and has even come to be regarded as a normal part of mainstream culture. The sexual revolution does not simply represent a growth in the routine transgression of traditional sexual codes or even a modest expansion of the boundaries of what is and is not acceptable sexual behavior; rather, it involves the abolition of such codes in their entirety. Carl Trueman
