Heaven right now but confused

I'm really wondering what's going on. Trust me, I'm not complaining by all means but my husband hasn't performed oral sex on me in about a year and all of a sudden, in the past couple of weeks, he jumps at the chance. He loves to watch me masturbate but when I ask him if he would like me too so he could watch, he said no that he would rather lick me. Like I said, I'm not complaining at all. Just was wondering if anyone has ever had this happen,like out of the blue.
