Rick,
I am under the care of Dr. Mulhall (associated with Memorial Sloan-Kettering in NYC) and following the injection therapy schedule of 2-3X per week. I will be two years post-op next month, and have been using trimix since Sept. 2008. The pills never gave me more that a partial erection that was not sufficient for penetration. The injections provide a normal erection that lasts more that an hour, and who knows how long if I keep stimulating.
Dr. Mulhall believe's that healing takes up to 18-24 months, so I'm bumping up against the higher limit. On occasion, I get a full spontaneous erection in the morning but it only lasts a few minutes. So I'm not sure if I've reached my ED recovery peak, or if there's more progress in my future. At age 64, other hidden ED factors that affect many men may start influencing the process and I won't know if it was the surgery or part of aging.
I'm in a loving relationship with my wife of 38 years, but she shows little interest in sex these days. So I'm more or less on my own and don't want to give up yet.
