Tried Something New Last Night

Last night I tried something new with my partner. I wasn't sure why but felt this sudden urge to be more dominant. Tied him up, blindfolded him, and then took control of the sex. Felt so powerful, sliding myself onto his hard cock while he lay there bound and helpless. Made him beg for release before finally letting him come. Was it just curiosity? Or do I have a hidden kink I should explore more? Anyone else ever try something completely out of character in bed?
