Restraints

I have been having fantasies of being tied down. I’m planning on talking to my husband about it. How did you bring it up? What were your SO reactions? I’m leaning more towards a a four point under the bed restraint system. Idk it just turns me on so much. I really hate being in control in the bedroom. My husband isn’t very adventurous so I’m nervous in how he’ll react. He’s noticed i like it more when he puts his hand on my throat or giving me soft bites. I hope he’s open to it.
