Agree with previous posts we certainly don't need the singular options for Anal or Rimming when we have the give/receive options.
Groups is a bit dodgey, but none the less informative for those looking for that service.
Kissing (without tongue), could lead to confusion where both French Kissing and it are selected. I'm sure if the guy doesn't want to use tongues the escort won't force him
As for GFE I think it is subjective, but still a useful option. I wouldn't see it as being linked solely with French kissing. For me I think of it as a style of appointment. Similar to how PSE is a different style.
I think clarity could be brought to it by having a detailed description of exactly what to expect/ not expect with each option.
