The absence of sex matters so much because sex itself is the supreme conciliator and salve of all conflict, ill feeling, loneliness and lack of interest. It is almost impossible to make love and be sad, indifferent or bitter. Furious perhaps, in a passionate and ardent way. But not – almost never – truly elsewhere or beset by major grievances. The act forces presence, vulnerability, honesty, tenderness, release. It matters inordinately because it is the ultimate proof that everything is, despite everything, still OK.
