Loss in sex drive?

Sidney • Not a Mommy yet but hopefully soon🤞🏻🤰🏻#futurearmywife 🇺🇸

My fiancé and I used to have sex a lot and by a lot i mean A LOT haha but recently it's went down drastically and I'm not sure what to do or why it happened. Does anyone have any tips or advice or anything? I mean it's not his fault it's mine but my sex drive just decreased suddenly.
