I tried all of the oral meds without notable success. I then used the pump and oral meds and was able to achieve a usable erection, but the process is uncomfortable and distracting. It hurt to pump up the penis and I used a manual pump. The idea of an electric pump motor seemed something out of my control. The erection is at best spongy and uncomfortable.
I tried Caverject and immediatly got an erection similar to pre surgery. No rings, no pumping, just a shot and things were looking up. The thought of the injection is far worse than the real thing. However it still takes some concentration.
I am still working to get things right. The Caverject is simple to use (premixed and contained inside the syringe) but at higher doses it can leave an aching pain. If I must continue to use injections, I will be investigating the "mixes", which reports claim have fewer side effects.
