So, i have been browsing through Wikipedia commons and found this guy Uploads by Richiex - Wikimedia Commons. He is able to cum just by playing with his balls (i will link all of his "testicular masturbation" or "scrotum masturbation" videos down below). I immediately tried it myself, and it felt amazing. I just in general think that balls are underrated and men should play with them more, but i never thought that jerking off your balls is so easy.
