I am experiencing severe burning sensations inside my vagina as soon as my husband's semen is discharged inside. I am having a normal vaginal secretion and never experienced it earlier during intercourse. Just got married 2 months back.

Are you also experiencing vaginal dryness, or any infections? There could be several reasons for this, First, I suggest you check with your doctor. She/he may recommend using a lubricant if there is dryness, or another over the counter products. Good luck and best wishes.

It sounds like an infection, so you need to see a doctor to find out what kind.
