erectile dysfunction
"I am a pretty fit 60 year old who had been experiencing some Benign Prostate Hyperplasia symptoms and had increasingly noticed a deterioration of sexual performance. I was prescribed 5 mg daily Cialis.  It was helping somewhat with the BPH though I decided that the cost to benefit ratio may be far better with another medication.  
The sexual performance benefit was another matter entirely and I couldn't be more pleased. The daily 5mg made me feel 30 years younger, the quality of the sex has increased dramatically as I am able to last much longer and ejaculate much better as well.  My wife is both shocked and pleased.  I am now splitting them in half and have noticed virtually no lessening of its benefit."
