Sex Problems.. HELP!!

So I’ve been with my husband for almost 6 years now, we’ve been married almost 2 years and have a 2 year old son together. Anyways, our sex life has always been killer!! 🔥😏 BUT........... lately it’s just really plain, vanilla, weird, boring, etc. 🤔 I used to get crazy turned on by him, and would just waterfall after just minutes of fooling around. 💦🌊 But now I can barely stay wet... I feel bored and feel like I’d just rather him quickly cum so I can go masturbate and actually orgasm rather than feel unfinished and time wasted. Why is this happening? This JUST started happening maybe 2 weeks ago, and since then it’s just gotten worse. (He has no idea I feel this way, I fake orgasms and we used flavored lubes because he thinks it’s fun and likes eating me out with it) HELP ME!!! 😩
