What does " GFE " mean to you ? ..Should there be a standard ?
Back in the days when I first started hobbying standard SP sessions did not contain kissing. Most SPs didn't offer this, as it was a reserved for a b/f type thing. So, GFE basically as I see it evolved to include LFK or DFK, YMMV but some form of kissing: that which was previously held back for a b/f-g/f only relationship. The 'just for the b/f" thing became BBFS. As a result there are many GFE SPs who, aside from BBFS, will offer just about any standard service a client would like.
The funny thing is according to oldtimers back in the 1970's and before (before I started hobbying) BBFS was often offered, but kissing was a no no. Ah, the joys of the pre-AIDS existence when almost all STDs could be cured with antibiotics lol.
When I see a girl who describes herself as GFE I tend to expect conversation and kissing.
