I've run across some exceptional providers websites but they don't mention their services. GFE, PSE, etc. I realize it's very touchy in how you ask. Is it appropriate to ask if their consultation fee includes a GFE? How would I word this touchy question and still be respecful of their situation? Thanks.

I still cannot figure out what they stand for, what is GFE and PSE?

For obvious reasons individual websites will not list "services" as is done on a TER profile and it is to your credit you consider proper conversational/e-mail etiquette. Simply making reference however to GFE or PSE is not usually considered in "bad form".

I should have added that the providers in question don't have reviews on TER which is what prompted the question. I wouldn't have asked if the girls had reviews. Thanks.

GFE Girl Friend Experience (thing this is basically full service with kissing)
PSE Porn Star Experience (no clue how this is different than basic FS)
