Insane sex drive...?

So I'm 8 weeks postpartum and my sex drive is out of control! Like before I got pregnant and especially while I was pregnant I enjoyed having sex but really didn't want it often (I was fine with once or twice a month, and I could have gone my whole pregnancy without it). Now I'm like insatiable! We finish having sex and I want more. I could do it 3 times a day and probably still want more.

Is this normal?! Has this happened to any of you?!
