Quote: To me doing what I guess is in the book and delaying any "O's" is like watching and helping a special food being made as compared to just showing up and eating it.
It's beyond watching the food. I think the author is saying it's more like having a wonderful meal and going on tasting and enjoying the food, savoring it, really enjoying the taste, texture, smells, sights for a much longer time, delaying the end of the meal.
I know that for myself, when playing by myself, I deliberately delay the O for as long as possible-- sometimes an hour or more-- because once the O happens, it's all over. The feeling of being right on the edge of the O is the most delicious part, when everything is humming, and you can go over at any moment. She's just saying that with this method not only do you stay in that very physically pleasurable zone for longer (some say "you can go on all night"), but since you are not focused on the O (which often means you remove your attention from your partner to focus on yourself), you can deepen and intensify the emotional connection. That is, if you see a deep emotional connection as something worthwhile having (I'm not sure BB does, from what you've said.)
