Guys growing up during classic porn era and guys who have been watching internet porn from age 10 may have different ideas of PSE. SPs also provide different levels of PSE. What could happen if a hardcore PSE guy meets a soft PSE provider? The guy may feel unsatisfied and the girl feels her boundaries being pushed. To make things easier, why don't put PSE into 2 categories, such as PSE and full PSE?
For example.
PSE: facefucking, rimming(client to SP), DSOT, light spank
Full PSE: gagging, hair pulling, DSOF, spank, light choking, rimming(both ways)
