what does DG, GFE or both include?
DG in this context is shower together, massage, and have the girl lick you all over your body, in addition to the other goods like BBBJ, 69, rimming, DATY.
GFE when it comes to C-Orgs generally means the girl will LFK, possibly DFK you and cuddle/be more of a girlfriend and provide a more affectionate session, than a "service" provided by DG.
Combine the two and you get the best of both worlds.
Reality is, it comes down to the girl. Some will not do certain things (rimming and DATY come to mind), differing levels of enthusiasm, skill, etc.
But overall for this org I've had a lot of good experiences.
