Sex help

Please ladies! I need all the advice I can get.

My husband and I have been through a serious dry spell. I’m 38 weeks pregnant and really want to bang this baby out. (Side note: my husband has been so caring and supporting and no pressure AT ALL for sex. He’s an amazing man)

Every time we try it’s uncomfortable, dry, painful and my husband says he almost feels like a wall in my vagina that’s not letting him fully enter me. He keeps saying that he feels like he’s hitting the baby’s head (is it possible? The baby is super low) I’ve tried lube but didn’t really help. It just gets frustrating and feels like a chore which just makes the whole situation harder and me and him feeling like failures.

Any advice at all? Any positions that help? Any lube recommendations (I’m super super sensitive to lube)?

I just wanna be able to have sex!!! 😫
