Ever since getting the mirena coil I've noticed that my vagina is quite dry. When I've been aroused in the past I've had no problem with lubrication but now I am nowhere near as lubricated down there. I literally have to apply lube every few minutes during sex. I really don't want to get rid of my mirena as it is the only thing that has helped with my horrific periods. I finally don't have to take Iron supplements anymore. Can anyone advise?
