What has made my sex drive sky rocket?

I know this is a crazy question but you all have no idea how annoying this has been the past 2 days! I have never been the type to want sex that much. Completely out of nowhere 2 days ago, it's like my sex drive exploded! I want it every second of the day! And me and my spouse can have sex but after a few minutes after we are done, I'm ready to go again! It's like I can't get enough! Idk what is wrong with me! I haven't changed anything? Does anyone know what can cause a sudden increase in your sex drive? It's seriously driving me nuts!
