How do i get my vagina not to be so dry during an before sex?csn i do anything and is there a reason for it

Lubricant: One option would be to try a lubricant like KY during intercourse. Also, there are over-the-counter vaginal moisturizers like replens which can help. As to why it is happening, it could be a number of things: you could need more stimulation during intercourse, sometimes women on very low-dose birth control pills have dryness. If the otc things don't help, see your obgyn.
