and didn't find too much guidance on these.

 
The closest that may apply to sexual activity for NE is nipple erection, which might mean her nipples get nice and big, but maybe she tries to get your nipples erected by pinching or sucking them.

 
SE is even more problematic.   Closest I could find is sudden erection.  Hopefully yours, not hers.

that seems reasonable is that these are referring to DATY and DATO.  (North Eating and South Eating).

The simple answer to this was provided in the ten year old thread I posted earlier, by GaG. To quote, in part:

 
“FWIW, these two terms are usually used in non GFE and non FS type sessions where playing with her tits, ass, and pussy are sort of taken for granted.”

 
The reviewer just means she let him get handsy with her breasts and butt/pussy. This especially makes sense in light of the “on the outside” remark. Means she let him touch her pussy but not get any fingers inside (FIV).

 
Because some happy ending, and even BJ ending, massage gals aren’t okay with mutual touch, especially below the waist.
