So we can assume that the transplant to your head went OK?
Brings a whole new meaning to the phrase, “You can have my penis when pry it from my cold, dead hand.”
From Robin Williams:

Mary Shelley’s Frankenstein meets the Penthouse Forum…I dunno…
Well that’s if you only got one. If you got one on each side at say your temples you’d have Boner Horns.

The ennervation that Qadgop mentioned is the big sticking point. To really make it work, you’d need to route the nerves from the appropriate regions in the brain - somatic, sympathetic, and parasympathetic - into the transplanted organ. And it really does have to be those specific nerves, because the way that the central nervous system integrates information is by knowing that specific “data lines” correspond to specific physical parts. If you just wire it into the arm’s nerves, it’d feel like a piece of arm.
It’d make shaking hands a tad awkward 
I said that first.
