Hello, no problem, 'tis a pleasure.
Eeeek, sorry pal, I can't say! I just made a kind of educated guess, having once been an amphetamine user myself (that stuff effects your sexual health, which is why I felt entitled to comment). You'd best ask your doctor about that one!
Maybe someone else will drop a comment, someone who knows!
thanks newdude for your comments. i know your not a doctor but how long before the penis gets back to normal.
I think it's a good idea that you stopped with the Viagra, and yes I think that your penis may be readjusting. Try some exercise, mild stimulant or aphrodisiacs to get yourself turned on... that may help.
I am no doctor, though, so try and find a professional opinion.
