My obsession comes from thinking about sex all of the time and it is a re-occuring fantasy, which as I get older becomes stranger and more upsetting. I am married with grown-up kids. I have never been unfaithful to my wife and never will be. But the fantasise seem to take a life of their own. I write poems about them, make up stories, fantasis when I should be working, reading, paying attention to important matters. Even now as I unburden myself I panic slightly about them.
