Well since you asked Paul_M I have had done (though not always specifically requested):
Lots of straight-up missionary position sex
My cock sucked until the top practically came off
Eaten more pussy than I've had hot dinners
Pushed my tongue up a willing girls backside until I thought my tongue would detach
Been cuffed and harnessed and had the arse and dick whipped of me
Beed ridden (quite harshly) by a dildo toting gal
Had a threesome where one girl stradled me while another (with dificulty) licked my balls
One girl let me wee on her
One girl let me lick her feet for an indecent amount of time
I visited a couple of TSs (use yer imagination)
I've requested doggy style many times
On a few rare ocassions I've asked for and mananged to perform anal (fairly energetically too if I may say so)
I've been led around on all fours by a dog collar (at my request)
I've licked boots and shoes
I've had prostate massages while trussed to a bedpost
I've provided more pearl necklaces that Sotheby's
I've had deep-relaxing massages with more FK than UK
I've had my face sat on
I've had my balls squeezed until they almost popped
....and once I had a wank while I listened to the "oohs and aahs" in the bedroom next door as the girl finished off another client
....and finally I.....aaahhh....lets not go there.
So there ya go Paul_M thats the sort of stuff I've asked for or the gilr(s) intuited I wanted
Hope this is of some assistance
