My Secret BDSM Fantasy with My Partner

I've always been proud of my ability to solve complex problems at work, but outside the office, I have a secret kink that has nothing to do with algorithms or coding. For months now, I've been engaging in consensual and thoroughly negotiated BDSM sessions with my partner, Sarah. We agreed on certain roles where she restrains me and administers mild punishment as part of our playtime. Tonight, when the moment came, we set up everything just right: soft leather cuffs that didn't hurt, a blindfold to heighten sensations, and a paddle for light spanking. I felt my heart race as Sarah guided me into position on the bed, her commands clear but gentle. Once in place, she told me to count out loud as she made contact with each spank, my ass stinging delightfully with every number. The sensation was both painful and exhilarating, sending waves of pleasure through me despite the initial sting. My breath quickened and I began to squirm beneath her guidance, anticipating more touches that would send fresh ripples of heat coursing throughout my body. We agreed beforehand on a stopping point, but as Sarah prepared for another hit, she asked if I was ready to continue or needed to stop. I responded eagerly, feeling an intense connection and trust between us. Afterward, we talked about the experience, agreeing that it brought us even closer together in our relationship. Is this normal? Should I be concerned about my enjoyment of these scenarios?
