Thanks, appreciate your response. Yes, my testicles did shrink - I'd say by at least 50%. And yes, I lost a good 2 inches in penis length. This has had tremendous impact on my overall negative self-body imagine. I'm remined every time I shower, urinate, or get un/dressed. Part of the fricken ADT journey. It is a lot of work for me now to masturbate daily compared to just a year ago when I did it 1-2 a day. Add to that the loss of libido and ED worsening. I was already prescribed 20+ mg tablets for ED. Thus, I think 20 mg daily would be too much, so I do try to take 20-40 mg of Sildenafil at least a couple of time a week for exactly what you suggest (blood flow). A small problem lately is that when I get up at least 2 times a night to pee, I have a slight erection, and the urine flow is slower. Good thing - I might be able to stop ADT after a year on since my PSA has been 0.02 awhile. Already see a slight increase in libido.
Could this be a sign of somewhat getting back to the way things were before.
