Lyric discussion by Jaded And Burned 

Cover art for Wasted Youth lyrics by Meat Loaf

This set of lines is a euphanism for puberty and discovering masturbation

But I do remember that it wasn't at all easy It required the perfect combination of the right power chords And the precise angle from which to strike The guitar bled for about a week afterward And the blood was so dark and rich, like wild berries The blood of the guitar was Chuck Berry red The guitar bled for about a week afterward, But it rung out beautifully And I was able to play notes That I had never even heard before
