Sex drive is dead, help??

I used to be a very horny person, I could get wet easily, aroused easily, etc. I was a virgin before I got married, and I've never masturbated. I got the implant shortly before getting married and now my sex drive is dead!!

I'm dry as a bone and my vagina won't get turned on no matter what we try. It's very discouraging, and with so many new factors I can't tell what the issue is.

Is it the birth control? Me? Both of our new inexperience? Should I try masturbating? I feel like there'd be no use because I'd be dry and uninterested by myself too.

Please help.
