Sex after pregnancy....Help!

After several weeks of waiting on recovery my husband and I decided to give it attempt. The first time it was uncomfortable and a bit painful. Afterwards I was sore until the following day. This was him barely getting the tip in. He managed to convince to try again at the 6 weeks mark. Due to the Covid-19 pandemic I have not had the chance to visit my OB. We took the risk and I endured during the experience as I had a burning sensation from probably using lubricant. After some time passed the burning stopped and it was good but my husband said it was too lubed he could barely have any sensation and it was only at entering he could feel satisfy. I am worried! Is this normal or am I not fully healed yet or will our sex life improve overtime?
