erectile dysfunction
"My latest thoughts on Cialis and Erectile Dysfunction   Benign Prostate Hyperplasia.
As I arrive at age 90, erection and orgasm with ejaculation/emission are much more difficult to achieve. 
Cialis 5mg daily still gets results including a sensitive slightly aroused penis but not a firm erection and at least one nighttime bathroom visit is necessary. Increasing the dose as high as 20 mg one time gets the same response as the daily 5 mg. 
As usual, YMMV."
