You are making the assumption that Viagra only is used for ED.    (of course, only medicallly dependent or men in 'emotional trauma'  would want a  45 minute erection).    It's a legal aphrodisiac for men.    I have know men injured, and it's not uncommon in military wounds, that really do need help - and can get it through their physician.  

Ban public advertising of prescription drugs.     In case congress missed it, we have a national drug problem with prescription drugs.       Let's see if there is a real profile in courage that might stand up to the drug industry.  I doubt it.  Federal/State/local approved drug pushers.   Nice.
