Well, not to put too finer point on it but, no, I actually said "they satisfy each other", I assumed from chatting to the man that sex, certainly in the way I think of sex, was not a part of the satisfaction.
erm.... ok, then. But I think you're bending over backwards now. If they aren't satisfying each other sexually, then what is he doing there? What other possible need could she fulfil? Money, an apartment, company...?
