There's this thing you can do it's basically fingering yourself and stretching your fingers out and pulling downwards it helps to not tear. I did this throughout second and third trimester and my perenium didn't tear

Your baby's head descending will stretch you out, relax your body, breathe baby out and don't rush it & it'll all have time to stretch properly. 💟

Lol that's a myth. I haven't had sex in over 7 months and I gave birth just fine. It has nothing to do with it. You'll be fine mama😊
