I'm thinking of removing French Kissing from my services.You can still provide a lovely GFE without
tongues right?
 I see someone several times a year who, halfway through the booking starts to ram his tongue down my throat. 
He's fine up to that point and I think he gets off on the fact I very obviously hate it.
 I turn my head away and clam my lips shut.

He gets away with this because he's fine at the start then, like clockwork the ramming begins (always when I am pinned under him)

Yes.. I know... 

I get not kissing per se, just think it would be slightly odd to omit it if you marketed yourself as offering a GFE.

Only if you think 'GFE' should be treated like a list of services with tick boxes next to them, rather than a general way of conducting bookings in a warm, affectionate and gentle way as opposed to a lot of very high octane and very overt 'porno' stuff that most would call a PSE. I don"t think this, so I don't think it's that odd.

I've done a booking this afternoon with no kissing on the mouth (because the punter didn't want it) and it was every bit a GFE, mostly because I have no idea how to do anything else

Maybe the term GFE should mean you get nothing but moaned at told no sex tonight i am too tired

LOL
