I would recommend you,to follow these measures ,to relieve the vaginal dryness
Drink 2 liters of water every day
Other remedies, are natural progesterone creams intravaginally,this step with your doctor approval,first
I do not recommend you,to use olive oil intravaginally, because it could produce a severe inflammation reaction, and this can be very dangerous.
But you can add canola,sunflower and olive oil to your diet, these will lubricate your body
Other important measure,will be the consumption of soybean oil in your diet, soybean oil increases the production of estrogen, (the main cause of vaginal dryness in older women are low levels of estrogen)
Other measure, is to insert a vitamin E capsule intra-vaginally.
Other lubricant ,over the counter,are Astroglide or K-Y, THESE LUBRICATE your vagina for several hours.
