Copper Pipe Fittings as Electodes

I have had the idea of using copper pipe fittings (smooth and very conductive) as cock electrodes. I am thinking of using a penis pump to swell my cock up to fill the pipe and using electrogell to ensure a good contact.

Any thoughts?

I've wondered about similar before and so have some play friends.. Though, the general consensus came back wondering if that type of copper was the same or safe for use as an insertable.. especially under power where sometimes things tend to exchange or break down.
