title: On call.  I've read your comprehensive discussion of erectile dysfunction, but one aspect is not mentioned: at age 74 (with a new wife, age 70), I can have erections, both with and without Levitra, but I have increasing difficulty achieving difficulty achieving ejaculation.  I assume this is related to ED and age, but wonder whether there is a solution.  I don't drink or have diabetes.  I do have high blood pressure, but it's controlled with Hyzaar and Plendil.
