Sex PP

Kr
Okay, this is it, I'm 4 weeks pp and after the minimum amount of sex we had during pregancy I feel like I'm a freaking virgin again.  I'm super excited to have sex, it's been WAY TOO LONG, but I'm also terrified, someone talk me down. I'm having visions of my insides become detached from one another when he's in there (I had a csection).  How long did you ladies wait after baby to have sex? Everything go smoothly?
