After 24 hours of an intercourse, there is a white discharge from the vagina of my wife. It appears as solid white clots and the wall of the vagina goes dry. This continues for 5 days. This happens only if the semen is discharged into her vagina. If I don't discharge the semen inside her, she doesn't suffer from any problem. Is my semen causing the problem. What is the white discharge and what is the solution to it? Please help
