My Secret Fantasy with My Husband

I’ve always been open about sex with my husband, but there’s one thing I never shared. Last night, while we were intimate, I suddenly had this intense urge to let him tie me up and take control. It felt like a wave of pure desire, overwhelming any hesitation. He tied me to the bedposts gently, not overpowering, just enough that I couldn’t move much at all. His touch was rougher than usual as he explored my body, pushing me further into submission. I wanted him to dominate completely, to push my limits until I begged for more. Is this normal? Do other married couples have these kinds of fantasies together?
