Back full force

So i just had my 3rd and last baby a little over a week ago and got my tubes tied. And my sex drive is definitely back already. I can not get my husband off my mind. I know have to wait 6 to 8 weeks because i had a c section. But i don't know how long i can last. I dont know what it is. I could care less about sex almost my whole pregnancy. But now I'm suffering lol. Idk if it's the hormones or knowing i can't get pregnant anymore. But anyone else currently going through this. How long did you wait?
