Well for my self, sorry for tmi, I'm never dry. To "wet" some times. My pain during sex is further up north Lol. Causing cramping for several hours after sex. So we try different positions, and some times, just do four play.
It's really need to stay the vagina wet at the time of sex. Otherwise, you'll feel pain.
Yes i would have excruciating burning during and for a long time after sex. My husband and I just use lube now and we've had no problems since!
Try some lube, otherwise you might have to just forego vaginal intercourse until after the baby comes. Hand jobs, other body parts, etc. are still OK on the list.
