At the risk of blowing a trumpet, I'm known for my extremely genuine and friendly GFE - which includes things otherwise listed as 'specialities' (O, both ways, kissing, french etc) in parlours.
So, my site states I GFE and I do when taking phone enquiries (say from contact magazines or listing only websites).........so I never know what to say when I then get asked "ok, so what do you specialise in?".
That's it - the whole package with a bit of something Je ne sais quoi thrown in.
There then follows a long, deep silence............
