The surgeon said pre-op it could recover but it would never be as solid. He also asked how it was at the time because that has some bearing. He was going to take the nerves on one side.
There was a constant slow improvement and if I was asked without looking or feeling sometimes it felt like it had recovered, there is something that stirs and gives a throb. I rejected treatment after taking Cialis a couple of times and not liking the aching shoulder feeling, I was wary of it anyway and didn't want to inject myself.
It kept getting better but only when I stood up or near stood. It never responds if I'm lying down. I bought a pump and it had an almost immediate effect of making it bigger and better shaped but hasn't helped spontaneous reaction. Admittedly I stopped using it fairly quickly.
In retrospect it's possible if I'd put a lot of work into it with different treatments it could be better. Also experimenting with different positions as gravity has a strong effect. To be honest I'm not hugely bothered and nor is my wife, I don't think.
I also got a urine leak but only when first stimulated although it's got a lot better. It seemed a bit of a black joke, show me a picture of an attractive lady and I'd wet my trousers, not much but more than you'd want. As I said it doesn't happen much now.
