Not interested in sex with my husband

Let me start off by saying that I have been with my husband for a decade and married most of that. I love him, we are the best of friends and have so much fun together. There is no abuse, I dont dislike him, none of that. But I have no sex drive. I feel like I could never have sex again and be fine, and he rarely initiates so we have sex maybe a couple times a month and honestly when we are having sex I'm basically just doing whatever i can to make him finish as soon as possible because I want it to be over. I want to enjoy sex and I want to have sex but then it feels like a chore.... I dont know if it's me and theres something I can do or if our relationship has just become platonic after being together for so long. I'm desperate for help/advice/others stories.... anything. I dont know what to do.

And not trying to be rude but would appreciate most advice from those in long term relationships. Its very easy to fuck like rabbits in the honeymoon stage and think you have it all figured out... lol.
