New Discovery

I just figured out something about myself that's making me feel all sorts of things I didn't know I could feel. It started when my friend asked if I wanted to watch some videos with her. We clicked on this one and suddenly, there it was, something triggered inside me, like a switch flipping. Before I knew it, my mind was painting pictures that weren't in the video at all. I couldn't stop thinking about how intense it felt when I imagined myself... submitting. It's not that I'm into pain or anything extreme, I just had this overwhelming urge to let go and be taken care of, to follow rules, even if they're playful ones between consenting adults. It made me hot in a way nothing else has before. But now I'm worried, am I the only one who feels like this? Should I talk to someone about it or keep it secret? Is this just something that happens and fades away with time or is there a community out there for people like me?
