Mines was the same before and after. It tightened back up perfectly down there. We waited 6weeks exactly. I did kegels everyday basically all day for six weeks n we both enjoyed very much.
I'd definitely wait until 6 week check up and docs okay to avoid the painful thing, esp if you got any stitches? And also you are VERY fertile, i know a girl qho didnt wait more than a week and got pregnant immediately after her son was born, babies were only 10 months apart! Ahh scary! Our sexlife was just as good if not better after my postpartum wait, i think him knowing we couldnt, made him even more eager after those 6 weeks lol
