Post-Partum TMI Pain??

I gave birth 9 weeks ago, unintentionally un-medicated (epidural didn’t work, didn’t have time to try again).

I want to have sex with my husband but every time I get turned on, my muscles “down there” ache! It’s not unbearable but it is very uncomfortable and I think sex will agitate it more...

I’m guessing it’s residual soreness from pushing (because it’s those muscles that hurt). When does this wear off?? Is this normal??
