As an avid fan of porn, I would say that a PSE experience would have to involve:
1) BBBJ, with deep throat for extra PSE points, TC if a MSOG session
2) Multi-position vaginal sex
3) Greek
4) Dirty talk, moaning
5) The girl's shoes/boots stay on
6) Finish is always somewhere on the woman's body, usually a facial
Anything less is just civilian sex.
