✓ it out.

With all the experiences i had , i never paid attention to this  
Now I know what I'm into ,   GFE ALL THE WAY  

I will be visiting Vegas in January  
Clear up your calendar

I like your ✓ -mark.  

...to use it sometime.

GFE has much more relaxed Atmosphere. Not that dynamic as PSE. If you Do GFE you speak more with the guy you are being with maybe some Body to Body massage can be included in the service and Lot`s of kisses.  
while PSE is not about being a Girlfriend to someone I guess. It`s more about being a private porn star  In the room.  
and services like CIM,COF, rimming,anal, some BDSM acts  and stuffs like this has to be included.  
Maybe I don`t have right . but I think this is how I would describe the two type of services.
