Megalomaniac-smashing is a stressful job so I guess one can't be too surprised when Ian Fleming's super-spy James Bond takes a break from saving the world to relieve some tension. I'm not at all shocked that DC would be so graphic in depicting the private moments of Mr. Bond because the Silver Age DC was all about smuggling things in under the radar of the Comics Code Authority.
I can imagine the horrifying slash fiction that this panel will inevitably inspire:
"Alright, Goldfinger. You expect me to talk?"
"No, Mr. Bond. I expect you to masturbate."
