erectile dysfunction
"Cialis worked for me!  I'm a 48 year old with a past history of benign prostate hyperplasia since treated, now experiencing erectile dysfunction.  Used it last night with rousing success. I would say I felt like a teenager again, but even then I had performance anxiety issues which went away once I got married. Good thing this wasn't around then otherwise I probably would have gotten myself in big trouble!  

Weirdest side effect though.  Whenever I got an erection, I felt this sensation come up the middle of my torso and it made me laugh uncontrollably.  The wife thought I lost it!"
