I am sexually active .(no stis) about 3-4 days before my period starts, my vagina burns on the inside and out. it's also painful stretchin during sex?

Vaginal pain: hello ~ this could be caused by a number of things but prominent would be bacterial vaginosis, fungal infections like thrush or a particularly dry vagina which can be due to inflammation or medication. I think it would not be an un-necessary enterprise to visit an OBGYN so that they can take a peek and see if there is anything serious going on or you could start using OTC anti-fungal cream.Thanks
