It may be weird, but for the past few years, my brain has thought that karate/taekwondo is considered porn. When I get exposed to something like a sparring session, my penis gets erect almost immediately after getting exposed to it. Even just thinking about it causes me to feel horny. In addition, I also get wet dreams over karate/taekwondo. It's been plaguing my mind off and on for the past few years now, and I need some reasoning on why it's the case for me. I'm aware this isn't an AskDocs forum, but I'm curious on why it's the case for me. P.S. I'm 14.
