I am new to the hobby and notice the K-girl ads that offer GFE Pluse. Can someone clue me on the difference?

Read the juicy details of the reviews. If the escort doesn't have reviews , don't see her. As a newb you should be only see well reviewed escorts.  

I agree with hiddenhills, read the reviews and stick with ladies that have reviews.

Stating that

Outside of Cali GFE+ is the same as GFE in Cali which means Daty, BBBJ and DFK, LFK are usually on the menu.
Again, read the reviews to know for sure.

It could be rimming, often times it comes with the K-girl experience but like the other guys said, only see a well reviewed ladies.

Thanks for the info.

The reason I wonder is that I notice there is a difference in price

Correct, again outside of Cali you'll see ads for GFE+ where the above is available. If it just says GFE some if not most of those mentioned will not be available, hence the price difference. Trust me, GFE+ is worth the extra $$
