Hi, for the past few weeks I've had a burning feeling at the opening of my vagina. It feels like a paper cut and burns when urinating or at the start of intercourse. I'm sure its friction burn after a lot of rough sex. My sex drive hasn't went away and we continue to have sex, it only hurts when we start having sex, we kind of have to force it initially but once we get going its ok. Afterwards it's back to burning sensation when urinating and that paper cut feeling. What can I do to make this heal?
