First time PP sex

Today my baby is 3 months old and my husband and I finally had sex for the first time again. I've been so afraid to because I have been so sore still since birth. I was always super sensitive before getting pregnant and way more sensitive down there now. I had an episiotomy and quite a few little tears the doctor couldn't stitch. I had "a very small birth canal" according to my OB and my baby was nearly 10lbs. My vagina went through a lot. It took a long time to heal completely though I was given the okay at 6 weeks to try sex again but I've just been too sore. Sex today HURT. We were slow, we used coconut oil and it was still very painful. Now I'm laying in bed about to nap with baby and I feel like I'm healing from birth again!!!! How do women start having sex just a couple of weeks after giving birth!? I'm on 3 months and don't know that I'll be able to do it again for a while.
