He won't do what I want in bed ☹️

We've only been together for a year and he has become sooo lazy in bed. He always wants me on top (which I love and I always orgasm) but it gets kind of routine almost boring. Sometimes when he does get on top he gets soft. His excuses have been he's too tired. He doesn't even do any foreplay with me. A few days ago we were both really horny (he wasn't tired) and I told him I wanted him to put the hand cuffs on me (we use to do wild BDSM stuff when we first got together which he loved). But he totally ignored it and just had me on top again. I feel almost embarrassed to ask him again, like I'm desperate or something. I don't want to sound like that. I want it so much I have been having sex dreams about being tied up by another man 😰 and I masturbated today thinking about it. I feel so pathetic. Help?
