@kberg333 industrial silicone is super cheap and guys usually apply themselves at home, or have a bud it applied on them, it falls more into a body modification fetish than a proper plastic surgery. I have seen injected dicks that still look appealing, even though the majority become an atrocity that has barely no use.
As for the methods you mentioned, I don't think I have ever seen an example, and based on a quick google search i just did, if i ever saw one it most likely passed as a natural dick.
