Arm Slide
A method of stimulating the head of the penis by sliding it along the forearm.
How to do it
Rest your forearm on a stable surface or hold it in front of you. Take the head of the penis and press it against the skin of your inner forearm. Slide the penis back and forth along the length of your arm. You can experiment with moving in different directions or changing the speed of the gliding motion. This technique works most smoothly on skin with little to no hair.
Why it works
The skin of the inner forearm is soft and provides a broad, flat surface for stimulation. Sliding the glans against this surface creates a different type of friction than a hand grip, distributing pressure evenly across the tip of the penis to build arousal.
