Confession of a Kinky Heart

I'm twenty-eight and have always been intrigued by the world of kink. My partner and I started exploring our interests in bondage, light spanking, and blindfolds about three years ago. It began as an experiment but quickly evolved into something much deeper. We both enjoy the power dynamics and the way they heighten our intimacy and pleasure. Last night was particularly intense, we tried out a new game where I had to navigate a room with my eyes covered while she guided me, leading up to some heavy petting and teasing before we finally made love in complete darkness. I feel so connected to her now that we're comfortable sharing these experiences, but sometimes I wonder if it's normal for others to have such specific desires. Do people often explore this far into the realm of kink? What advice do you have for couples just starting out on their kinky journey?
