More from my memoir

In which I have radiation and an affair

Me in 2004, on my 40th birthday

      My husband and I had the kind of boring, married sex that was really nobody’s fault, but was nevertheless made worse by the fact that our marriage was slowly disintegrating. Often, right after we’d finished, I’d consider how empty I felt and think, well, maybe I’ll have an affair. But I never actually thought it would happen, and if it were to, I especially didn't expect it to ignite in the middle of radiation for breast cancer, which has surely been among the unsexiest events of my life thus far. And yet that is precisely what occurred.
