A Recent Experiment

I'm a grad student and I recently experimented with light BDSM during a date night with my partner. It wasn't something we'd ever discussed before, but I felt a sudden urge to explore it together. We used some restraints and role-playing elements that I initiated; she seemed intrigued by my suggestions. We agreed on strict boundaries beforehand, and everything was consensual. Afterward, there was a mix of curiosity and concern about our relationship dynamic. How do you handle unexpected kinks or desires in an otherwise healthy relationship?
