Hi bobbart,
First, I would suggest seeing a Urologist who specializes in male sexual dysfunction and have him evaluate your ED.
Also, have you considered an IPP (Inflatable Penile Prosthesis)?
I developed ED in Post-Prostattectomy in February 2004 and the
"standard" ED Treatment Modalities (Viagra, VED, MUSE, Injections)
did not work to my satisfaction.
In December 2007 I was underwent the Coloplast Titan Penile Implant Procedure and, thankfully, it completely corrected my ED and restored both my sex life and the emotional intimacy with my wife of 45 years.
This is essentially for men like myself for whom the standard ED
Treatments have not worked.
Discuss this with your Urologist but, at the end of the day, the final decision is yours and yours alone.
Best of luck.
Bob
