Spice up sex???

My husband and I have been together for 6 years. Our sex used to be just fine but now it has gotten old and is so plain and the initiation feels almost awkward. When he does it, he makes stupid jokes and stuff first...like it’s not a turn on and I told him that. When I initiate, I try and make it sexy. Kiss on him, grab his dick, rub it, and suck on it. I can’t even remember the last time he’s gone down on me....it’s been well over a year! I’ve talked with him about it, told him I like him going down on me too, and he said he would but just doesn’t! He doesn’t rub on me sexually anymore, and the sex is so basic and no new positions, dirty talk or anything exciting! I’ve tried talking to him and tried different things and it’s just not good anymore! Idk what to do! 😫🤦‍♀️

I’m into choking, blindfolds, etc. and he always voiced that he thought that stuff was weird...so I can’t bring that stuff into the bedroom. 🤷‍♀️
