Hi Jeremy, very interesting idea. I have thought about it before.
What I do know is this, you will certainly make a strong association to whatever it is you are thinking about during this time. If you've ever read about Neuro-associative conditioning or NLP in general, you will know that the brain makes associations all day long. So, if you want to motivate yourself to take action towards something, you create an intense pleasurable emotion and then think of the task that you want to accomplish at the height of this emotion. You will thereby create a link between the goal and pleasure.
It would therefore seem plausible that if you thought of your goal at the point of orgasm that you could create this link. Whether it's a 'strong intention' in new-age terms I don't know. Some LOA peopl say that you are attracting what you are
feeling, not what you are
thinking so really you could just be attracting more sex, which isn't the worst thing in the world
I guess the challenge here is to get your mind out of the gutter for a few seconds to think about your goal
Just kidding, I'm sure it's not in the gutter. Either way, I would say it could move you toward taking action in the direction of your goal. Interesting stuff.
