Boxer Tap
A technique involving rhythmic tapping on the underside of the penis through tight fabric.
How to do it
Wear a pair of snug, comfortable underwear. Once erect, position the penis so it points upward, pressing the underside against the fabric. Use your fingers to tap repeatedly on the underside of the shaft through the material. This motion can be used as a way to build arousal or as a primary method to reach climax.
Why it works
The tight fabric creates constant light pressure against the sensitive nerves on the underside of the penis. Rhythmic tapping introduces a percussive sensation that stimulates the nervous system differently than rubbing, focusing energy on a specific area to increase sensitivity.
