Husband turned into a prude

Over the last year my husband has become such a prude. We still have sex, but I just don’t enjoy it. It is always the same and never any switch ups. I almost always have to initiate it. He used to be more into exploring and keeping it fun. Now it’s just routine. I can count on one hand how many times I’ve orgasmed in the last year from him. Now I have to resort to watching porn and doing it myself. I’ve tried to talk to him, I’ve tried making suggestions asking if there is anything he wants to try, etc. I am very open sexually and willing to try almost anything. I want to enjoy sex with my husband. I don’t know what to do. He always says he is happy with our sex life. What can I do other than being flat out mean and saying I’m not satisfied sexually??
