Seriously guys, if I've mentioned it once, I've mentioned it 100 times, get with the new age times and technological advances.
Viagara is from the 80's.
Yes you can still get a script for Viagara and Cialis, but pfffft...........if you're really serious get the gel. I've given enough hints in the past, so clearly I now need to spell it out for ya
Consult your local Dr who will refer you to a Specialist which will require a series of pathology tests to pass the entrance exam and once there, you'll be driving your 4wd like a young man again.
Warning: if conditions persist, then consult your wife or girlfriend or go back to the Dr
