I use to be wet all the time especially during sex. i gave birth vaginally to my son 6 months ago and now i am dry down there and i rarely get wet.

Estrogen: After giving birth, especially if you are breastfeeding, your estrogen levels go down and it's estrogen that keeps the vagina moist and well lubricated. You might consider (especially if you are breastfeeding) to talk to your doctor and get a Rx for vaginal estrogen cream or ring or pill to help bring it back to life. Not to worry though, likely due to childbearing and will get better!
