Marriage Dynamics

Been married for seven years now... we've been getting into this BDSM stuff a bit lately. Started out small, maybe tying each other up or blindfolding, but things got more serious recently. Last night... well... my wife and I were exploring some limits... she's really taken to the dominant side of things, enjoys being in control... it was different from what we usually do... kind of liberating for me actually, letting go like that... wondering how others manage these kinds of dynamics over time... but mostly just here to confess, not sure if I'm ready for anything deeper yet. Just going with the flow...
