I asked if a girl did GFE and she said yes, but then when I got there she only did topless, and she didn't even know what GFE stood for.

Reading reviews should tell you what to expect. If you see unreviewed providers it's anyone's guess what you'll find, that's why it's called taking one for the team.  There are always exceptions but discussing sex before you meet should get you hung up on.

GFE is basically a marketing term at this point. There are so many definitions that it has close to no real meaning. It means everything from BBBJ to "I'll be super nice to you and love cuddling" depending on the girl.  

In this case, it sounds like you asked a massage girl if she was GFE and she said yes, which probably, to her, meant she would be happy to chat with you about your life while she jerked you off.  

It means nothing. Read the reviews to find out what someone does, and if that matches your expectations, go for it

and everything will go nicely.  Ads are often unclear.  You need to check her reviews & beFore final selecting you'll need VIP
