sex after birth

when does sex feel normal again? I've had my 6th baby recently, like 5 weeks ago recent, & I'm terrified of the thought of having sex. i'm scared it'll feel like a gaping hole down there (not even exaggerating or joking, these are my real thoughts & feelings). I'm scared sex will not please him AT ALL & I'll feel "loose". he knows the 6weeks check up is next week & you can tell he's itchin' for sex but I'm just not ready
