Have you wondered how porn would look like if everyone paid for their porn? Now a days, there isn't as much stigma and there are gorgeous girls who are willing to extreme sex acts in the beginning of their career.
Back then you would have to wait months or even years for a girl to do her first anal. Today, many girls begin anal of the bat or few months at most. Interracial was something a girl would do later in her career and it was considered a big step in their career and would come atfter anal at sometimes. Nowawadays that would be considered racist.
Today, there are a few select women stateside (Emily Willis, Jane Wilde, etc) that get consistent work while many other gorgeous girls who left out.
The amount of hardcore gonzo porn would put the golden age of late 90s to mid 2000s to shame.
Only LP and Rocco put out these type of scenes.
Oh well, one can only daydream.
