36+ years of jacking off and I've never needed lube. Hell, I've never even done it the "normal" way. Instead, I have always massaged my dick through several pairs of tighty whities, or diapers.
I actually made a similar posting asking if my method of masturbation was normal... masturbating in my bed, face down, rubbing my index, middle, and ring fingers together through my boxers. I only asked incase there were some medical concerns I was unaware of...
