GFE and PSE mean different things to different guys and SP's. Heres my breakdown on the terms and the goodies offered:
GFE = BBBJ, DATY, DFK, MSOG, Pearls & Russian
PSE = All the above, along with other treats such as greek-styles and BBBJTC and facials
The best way to put it guys, your girlfriend doesn't slap a rubber on your man-hood when she gives head, she does a BBBJ and she does DFK.
But girlfriends rarely do anal or facials. They only do it maybe once in a blue-moon and normally just to shut the boyfriend up.
But as we all know, not everyone follows the above definitions properly and it would be impossible for us to police it.
