When I was younger, before I knew what masturbation was, I would scroll through Youtube watching videos of scantily clad women lounging around. It gave me a good feeling down there, so I continued. One night something different happened though, and I remember it vividly.
I was in bed, wearing just a pair of boxers, watching this particularly attractive Japanese woman lounging around her house in a white bra and panties. For some reason, this video in particular made me feel better than usual. Around 2/3 of the way through the video, I felt my balls tighten and I felt my boxers grow wet. Initially I thought I peed myself, but It was sticky instead.
I now know that that was in fact my first orgasm, but unlike all others to follow it, I didn't once touch my dick.
