To get it completely from its drooping state to an erection, I’ll perform the movements to maintain the erection. My fingertips make a hook shake and stand it up, and I start touching the portion called the “shaft”. I don’t nudge the delicate glans. From the base of the cock to the joining-point of the glans, I use all fingertips from thumb to pinky, I stimulate it with gentle movements akin to with a piano or flute. Gently thrusting, a barrage of more and more. Having particularly practiced the grip on the cock, touching the point gives a feeling of expectation for the erection. My fingernails have been trimmed short. I use a whole-body tapping and this “tip-tapping” caressing technique.
