I don’t understand why you separate the two?
Arousal is part of sensation. If you let it flower holistically, then the whole body partakes of that sensation, and it flowers and withers in a few seconds or minutes.
I am not speaking about acting out or acting from arousal. - Just the nonjudgemental observation of the movement of arousal as it flowers through the body and dies away; like a wave crashing on the shore.
As I keep on saying: there is nothing wrong with arousal or sensation. You are judging it from your own thinking because you have been lost in desire before, and you don’t want to get lost in it again. But it is only when our thinking comes in and tries to continue that state of pleasure or sensation that the problems begin. And the judgment of sensation by thought (as “seduction”, etc) is just the perpetuation of pleasure in a different form.
