Just Curious About Kink

I recently started exploring BDSM as a software engineer. It's been surprisingly intriguing and somewhat addictive, but I haven't told my wife about it yet. She might not understand the appeal or worry unnecessarily. Today, I tried blindfolding and light bondage during sex, which was thrilling in ways I didn't expect. Can anyone share their thoughts on how to introduce this interest to a partner without freaking them out?
