Porn is effective if you really want to show your provider PRECISELY what you want to do and how to do it (or how SHE should do it.)
Judging by the play by play I have been reading in some of the reviews on this website, Many of the popular antics and acts that seem to comprise the main course of these sessions had their origins in the steady evolution of porn that happened starting in 1999 and continues thru present day. Consider several specific acts:
**WARNING** Explicit content to follow, viewer discretion strongly advised (....I have always wanted to type that...)
Porn single handedly made Anal sex mainstream and routine.....before the early 1990s, ANAL was a specialty act, and fewer people in society engaged in it with any frequency. That changed in the mid 1990s with the advent of Anal themed video series.
Before 1999, the vast majority of pornographic scene cumshots were external, usually on the boobs, butt or face. Starting 1999 and accelerating throughout the early 2000s, open mouth cumshots and authentic swallowing proliferated throughout most porn studios. Snowballing soon followed.
In 2005/2006, several adult production companies popularized throat fucking (known as "gahhh gahhh gahhh" films).
Gang Bangs were introduced in the 1990s (who can forget Debi Diamond), but they really proliferated and exploded to become standard components of every major Gonzo release throughout the 2000s into the 2010s and beyond. This is why it's now a common FEMALE desire to be with 3 or more men at once.....prior to 2000, this wasn't as common (but still existed.)
People who grew up watching this stuff, particularly on the web, during their formative teen years developed proclivities and desires my generation never had, until our later years. I grew up reading playboy and penthouse....today's 20 somethings (born around 1997 thru 2003) have grown up watching on the internet all of the above stuff.....this can't be good for the overall health of the species. But it sure makes for livelier multi-hour sessions.....
