No risk at all from the radiation - there is no residual radiation after treatment.
I have never seen a warning about lupron or Casodex (bicalutamide) effects on partners, and as far as I can tell, they are not excreted in sweat or saliva, only in urine and feces. If a man has handled broken pills of Casodex or Proscar, it is a good idea to wash his hands well before touching a pregnant woman.

Probably not. While the testes still may produce some sperm after recovery from the hormone therapy, there will be no semen to speak of because of the radiation therapy. The semen from the prostatic fluid and seminal vesicles is needed to carry the sperm and create the right chemical environment for fertilization. Theoretically, the small amount of fluid from the Cowper's glands could carry out some sperm. Some men freeze their semen before radiation or prostatectomy for this purpose.
It is a use it or lose it situation from what I have heard. I have taken daily Cialis since before I started Proton Treatment after a suggestion that it helps maintain blood flow to the nerves critical to sexual function. I would suggest get a pump, plenty of oral, and if all else fails the best implant you can get. It usually takes at least as much time as you take hormones for you to recover from their effects but there are small muscles in the penis that will atrophy permanently if not used.
