If Superman is nearly indestructible, so much so that everything from bullets to missiles ricochet off without a single scratch, wouldn't that mean that his body would feel completely ridged to anyone that wasn't him? I imagine that his skin would have the same consistency as stone. Just because he is indestructible, does that mean his skin would still have the elasticity of human skin? For instance if you were to touch the cartilage part of his nose, would it move or feel like steel? If this was the case, you would think that it would be an issue seeing as anybody who might so brush into him on the street as Clark might be suspicious as to why his skin was so rock solid. And poor Lois (or WW) having to kiss lips of steel!
Well, I know it's somewhat of a silly question, but if you have an answer please enlighten me.
