No sex drive

The title explains it all...

here's a little background: I'm 25, I have a 4yr old and 2yr old. I've been with my husband for 7 years. For like the past 3 years I've had zero sex drive, I don't get turned on, sex feels like a chore. I feel bad for my husband bc his sex drive is really high and im just never interested idk why. Also I'm not on any medications.

Has anyone else gone through this and can help me find a solution? TMI but I used to enjoy masturbating more than sex but now that doesn't interest me anymore either.
