My relationship shifted from spicy to plain and I'm struggling to fill the void

Okay, so my relationship started out like a spicy taco with extra hot sauce-kinky, exciting, and full of surprises. Now? It’s more like plain oatmeal. We still love each other, but the BDSM side of things has fizzled out, and I’m over here missing the thrill. I don’t want to push my partner into anything they’re not into, but I’m also not sure how to spice things up without making it awkward. Anyone else been here? How do you reignite the spark without pressure?
