Shhh! You have to admit that Plenty O'Toole sounds like wanking slang!
Well it is still a sexual innuendo, MHarkin. Plenty O'Toole suggests plenty of a tool, in other words a large penis.
This is a rather interesting one. We find out in Dr. No what Moneypenny prefers in the bedroom...
Bond: Moneypenny! What gives!?
Moneypenny: Me.... given an ounce of encouragement.
... oral sex?
Nope. "What gives?" means "what's up?" and when Moneypenny says she gives, she means she gives in, she will submit to Bond. Giving in this sense, is like "giving way". If you push a stuck door long enough it "gives" and you can open it.
Bond: I was right, I couldn't miss. (refering to mole on thigh)
Domino: I'm not with you!
Bond: Oh, you soon will be.
Yes, plus after they have sex underwater, he comments on hoping they didn't scare the fish!
I also thought that another obvious one is from Tomorrow Never Dies:-
"You always were a cunning linguist, James".
