A lot of people hold their breath as they hit their crescendo just as they climax. If you deeply, rhythmically inhale exhale it will extend and delay your climax. It makes it very 'primal'.
When I am giving oral, (do I have to say it? to a woman, Jackasses I heard you thinking it.) I will stop when I hear her start to hold her breath, for a couple seconds and say 'breathe'. Then resume. I keep this up untill she freaks out and explodes uncontrollably or follows directions and explodes uncontrollably. Either way its a Big Bang. LOL
As a guy you can delay by tucking your chin to your chest hard and deeply breathing in nose out mouth.
Havent read that particular book, thanks more reading to do. Oh well, they are always the favorites on the bookshelf for the curious.
