Hi. Thanks for the query. A decrease in oestrogen hormone level can cause vaginal dryness. The decrease could be due to menopause or perimenopause (a transition time before menopause). The other possible reason could be use of certain soaps, lotions and perfumes which can disrupt with the natural balance of chemicals in your vagina leading to dryness. Kindly visit your gynaecologist so that he/she can carry out certain tests to confirm the cause. By doing so you can comfort your partner and enjoy the intercourse. Hope this helps. Take care!
