Thought I'd join in, after lurking for a good few months.
I like being spanked and rough sex, I also like slow sensous, almost tantric, sex, all with my gorgeous husband of many years who is more than happy to indulge my "sub" side.
My favourite fanstasy is of being a scullery maid or somesuch in a big country house, hubby is the man of the house who has me summoned for his pleasure whenever he desires. I have to wear a long virginal white nightgown and brush my hair out so it falls around my shoulders. He's stood there in a long white shirt and breeches, holding a riding crop.
The thought of being savagely ( but tenderly) taken in front of a roaring fire really gets the endorphins flowing!
It all sounds a bit mills and boon now I've written it but it works for me!
