I had Cyberknife in January 2016 and noticed that 'morning wood' was affected after two weeks with a steady onset of ED.
To normal stimulation such as porno, all I get is the feeling of blood rushing but no movement per se. I can get a sort of chubby to masterbate (yawn).
OTOH if I take 20 mg sildenfil, I can actually get a stiffy with my so called partner.
My question is the following
Will I progress to total ED,
Does it even out so to speak where I will have some erectile ability or do erectile function go away totally,
Will occasional use of ED drug preserve ability of blood to flow through to the penis, and do I need to use it daily?
I am quite surprised and happy that sildenfil has the desired effect. But what do men experience in the long term?
