erectile dysfunction
"I cut one 50mg tablet in half and tried as an experiment and I was able to obtain and keep an erection.  I had no side effects.  It was so nice to have a stiff erection.  Although the 50mg tablets worked, I would get some of the side effects... not unbearable.  I tried 12.5mg and I could tell I was getting an erection but the sensation did not seem to last as long."
