I am kinda new at this stuff what does pse mean?

Go to the Newbies board for answers to this and many other questions.

PSE means paying anywhere from 3 to 5 times the fee you
would pay one of our local Ladies for an experience that MIGHT
be marginally better and often times isn't the equal to that
which is available here everyday.God bless our Philly Fillys!!!

It's in the list of acronyms to be found on the newbie board.  Literally, it's the type of session with a provider that a guy would expect to see in a pornographic movie.  It's usually contrasted with the GFE-- the Girl Friend Experience.  A nice warm intimate night in which the sex wasn't the overwhelming part.

I've actually found the best sessions are both, so I shy away from these terms.
