Just a bit of an overshare here I suppose, so you can see how different experiences are even for same person.
1st baby I don't think we slept together after I got first got pregnant tbh, he was much older than me, (still is!) And whilst this is gross to say, I think seeing me as a woman, not a teenager really put him off me. He was desperate to get me pregnant too.
So I had sex first time after we broke up, before DC first birthday, so just before a year.
Second and third babies and 8 weeks with each, no stitches, just very bruised and sore.
I was a bit too keen to be trying to do other stuff for DP and he didn't want too, I was convinced it was because he then like exH found me gross, but he sat me down, both times, to explain how he wasn't going to enjoy feeling like I was performing out of duty almost, plus we were both tired etc and we'd get our groove back once time was right.
He was very reassuring, even though I was convinced with hormones and previous experience he'd leave me.
I'd definitely take any pressure from yourself and see what happens when you're comfortable.
Even with no tears and stitches, sex was quite uncomfortable for the first few times. Next time I think we'd wait until 3 months, just to really heal.
