Today Rosario and I had sex from midnight until four-thirty in the morning and I clocked her again. She came ten times, I came twice. And yet the time we spent making love was longer than yesterday. Between poems (as Rosario slept), I made some calculations. If you come fifteen times in four hours, in four and a half hours you should come eighteen times, not ten. The same ratio goes for me. Are we already in a rut?
