Struggling with Kink Curiosity

I'm nonbinary, married for two years now. Lately, I've been feeling a deep curiosity about BDSM dynamics that feels really out of character and scary. My spouse is supportive but also wary, they're not interested in anything too intense or permanent. Tonight, we tried something light: blindfolding and some gentle restraints. It was exhilarating yet terrifying. How do other couples navigate this? Is it normal to feel both excited and deeply anxious about exploring new kinks? What advice would you give?
