[X-Men, Marvel Comics] Its been show that everything down to even his blood becomes metallic when colossus transforms sooo does that mean if he we're to whack off any metal form that his sperm would come out metallic also? would it still be viable? could he get someone pregnant in metal form?

Only Collossus's tissue turns to metal. While in his metal form his bodily fluids are converted to energy. In the comics he doesn't need to eat, drink, or breathe while in his metal form as he is sustained by the energy of his form. Several times he has done this for months/years at a time.

(It's only in the Deadpool movies that he eats/drinks/pukes. The Deadpool movies are currently considered non canon to any other marvel property)
