still having post partum pain 🙁

I am extremely embarrassed to be posting this. So please no harsh comments or judgement.  My husband and I haven't had sex since my third trimester. Our daughter is five months now. Five. Months. We haven't had sex at all. In FIVE months. I am still in so much pain where the tear happened. I was told I had a very, very small tear. I just don't know if it's normal to still have so much pain when we attempt to have sex. 
He barely is able to go in, and I'm already whimpering in pain. We do use tons of lube so it's not a lubrication issue. Or maybe it is? It's a water based lube if that matters. I just am not sure if this is normal? Is the pain something I just need to push past until it's better? I just don't know what to do 😩

Yes I am still breastfeeding. I am too scared to even insert anything in there ): it seriously hurts so bad I feel sick
