Boyfriend suddenly a horndog?

My boyfriend is 33 and we have been together for 4 years. We use ti have sex maybe 3x-4x per month. I have a high sex drive, and his was always lower than mine.

Well the past 2 weeks have been different. He can't get enough of me. He asks to see my boobs in public places(never has asked before). He literally cant keep his hands off of me.

He is trying all these new things in bed. He even went down on me( he NEVER does this..with any woman.) Oh and he literally will try to make me orgasm at least 3 times before he will even try to get off himself. Sometimes i just want a quickie. But every time has just been ALL ABOUT ME and sometimes he doesn't even finish. (Sry, but I hate that).

Am i freaking out thinking there is something fishy or could he genuinely be loving me?
