You describe some itching, an odor “like tuna,” and a creamy white discharge. This sounds really classic for bacterial vaginosis (BV), which causes vaginal discharge, irritation, and a “fishy” odor, especially noted after sex. This diagnosis is made with an exam and microscopic inspection of the discharge; it’s then treated with an antibiotic.
Please call your primary care provider or gynecologist, tell them you suspect BV, and get it checked out. BV is not a venereal disease, but an overgrowth of a bacteria that belongs in the vagina. At times the overgrowth can cause the symptoms you describe. It isn’t really harmful, but it is bothersome.
Best of luck!
