To me GFE means more kissing cuddling and talking, PSE is mostly about hard core fucking, there is no hard and fast menu for either. Greek, CIM or any other activity might happen with either GFE or PSE it just depends who your with...YMMV. Just find someone who interests you and read her reviews. When you meet, don't have a list of positions and activities you feel you need to do, let things flow naturally and if you chose well you won't be disappointed.
So I'm fairly new to the hobby and would appreciate any help with understanding the difference between these. In short, I have a good understanding of the gfe experience, so am really wondering what is additional and/or different about a PSE?
Thanks in advance for any help.
Happy Hobbying
...PSE includes Greek (anal). Some will say it's also the vibe, with GFE being more doting and affectionate and PSE being more carnal and high energy. There's debate over whether CIM/COF is PSE or (naughty) GFE.
Regarding the Greek session. Just because she is ad'ing PSE I don't think necessarily means she will visit Greece. There have been many discussions about the difference between GFE and PSE, and opinions are many. It kinda depends on what your expectations of the PS experience are. I would say that GFE is probably a more loving type session than the PSE, but we could debate this question for years, and not reach a consensus opinion.

...but a GFE is like you said; "loving/caring/connection". When I think of a PSE, I think of non-stop sex, in every position, from the minute the man walks in the door.

Agree GFE is more kissing, cuddling... you leave wishing she was really your GF & not an illusion. PSE, is HD sex... you F*ck in every way known to man. Maybe leave shaking your head like what hit me!

To me, it seems fairly simple to tell the difference.
While some service offerings may vary, Greek, CIM for instance
I think the big difference is sensual Passion you would expect to get from a Girlfriend opposed to Carnal Sex you would expect to see in Porn movie.
But, again, I'm new, i'll leave it to others to debate it.
