I like both types of sessions but generally prefer what I would refer to as "GFE" but sometimes some PSE is thrown into a GFE date. It really is based on mood at that exact moment and also what the provider is into, or not into.

PSE all day.....facials & video

way back when I started this hobby porn star experience usually meant wild nasty gross sex, ejaculating on her face and whatever.
Girlfriend Experience used to mean she came over and acted as if she was your girlfriend, talking, cuddling, kissing, sleeping, whatever. Or you guys went out on the town, like a date.

Depending on the hobbyist, what the hobbyist wants is all over the board. What is PSE for one is different for another.
I understand we want some base lines for comparative purposes but best to know what you want without the labels. Go pay them money and find a provider that you like.

I had a provider who I couldn't tell the difference  
I did a GFE and then 2 sessions later I did the PSE with her. I couldn't tell the difference.
And that's not a put-down. She was just so sexy and nasty she basically gave both energy on both types of session. She loved being nasty and she loved making out.

I second that! But, definitely not with the OP.
