Hi,
Congrats on finding the forum and website and putting it to good use. I'm glad to hear your husband is doing well post-op.
The wife of a long term survivor put together some pages about how to deal with impotence post bladder removal, see:
blcwebcafe.org/impotenceguide.asp
Hopefully there's something helpful there for you.
The most important question is, what was the stage of the cancer? That will give an idea of the prognosis, however the fact that no further treatment was recommended (like chemo) means to me that the cancer was confined to the bladder. That's a good thing!
Your husband is very lucky to have you.
Wendy
