I have had pretty good luck with erections since surgery yet am still diligent about using the pump for rehab. I have never tried the rings. After using the pump, the little guy is engorged but is not a full erection. However, if I combine the pump with erotic thoughts/images, the erection persists. I should qualify this by saying that persistence is not yet near pre-surgery levels, though manual stimulation will keep the erection going. I conclude from this that the venous valves closing are a consequence of erotic thoughts and sexual stimulation, and that the pump itself does not provide this sexual stimulation.
I should also add that the erotic thoughts combined with the pump achieves penile bloodflow that I cannot achieve the the pump alone. No matter how much I pump, there is a bit of extra length achieved with sexual arousal that the pump alone cannot create.
