I've asked something similar on TERB I think....
GFE: Most important for me is LFK/DFK. Unfortunately its not an option that most sp.'s commit to until they meet the client. I've had one of two that strictly do not LFk at all, and definitely no DFK. I enjoying kissing during the act. For the majority most sp.'s offer LFK/ DFK in their own manner.
PSE: To me is when you opt for CIM, COF, COB,... I consider anal part of a PSE experience also. Only because I wouldn't get excited if a girlfriend asked me to fuck her in the corn hole, or shoot cum all over her face. Im not really into the PSE style. Tried it, and it just not me... jesus there was cum on her face, her arm the bedsheets (that I'm sleeping in), the floor.... jesus it almost seemed like we should have rehearsed it before trying it. The anal thing (my dick in her ass) I tried... just doesn't seem natural. I felt dirty afterwards... LOL... !?!?! Squirting.... I find to be something as a PSE. I find this can be quite fun and if Im in the mood, I can be a turn on. So long as she's not built to be like a pressure washer.
Basically when i book, I look for what catches my eye, Then good reviews (if there are none, I love TOFTT)... CIM, COF, COB, Anal, MSOG are not deal breakers for me.
Deal Breakers: Def no LFK/ DFK, Smoker, No english (unless I'm in Quebec city).
