bootheel, I am 5 1/2 months post surgery and having the same troubles. I can only manage an almost usable erection using the pump. The rings have to be very small to work at all. Are you using the smallest ring that you can possibily get on? It seems you have no veinous control, hence no ability to retain the blood in the penis. Veinous valve function must come before/or with the ability to get erections, so we can keep it erect when it does happen. It seems that some of us will take longer to regain what is lost in both areas. You are at the 1 1/2 month mark, which is way too early to see return of function in the majority of cases as posted here. There's an occasional report of very early erections, but more to the norm is from 6 to 18 months for recovery. Your using Viagra and the pump is a good start at rehabilitating. Keep pumping up twice daily, if possible, without rings to achieve blood flow and infusion in the penis, until recovery is complete.
What type pump and rings are you using? Some people have had to use 2 rings of the same size to acheive a firm enough erection for sex. Of course, you still have the penile injections to try. Most start trying them at the 3 month mark. Most men respond positively to some form of them, even if they have no veinous valve action yet. It's been said here that the best treatment for recovering function of the veinous valve control of the penis is first injections, then the pump, and last Viagra in order of effectiveness. The chemicals artifically activate and close the valves, providing good therepy by retoning and stimulating the nerve memory of using them. Hope this can help in some way.
