My vaginal discharge smells like sperm what does it mean?

See answer: Vaginal odor may vary throughout your menstrual cycle and may be especially noticeable right after having sex. Poor vaginal hygiene as well. Bacterial vaginosis (an overgrowth of normally occurring vaginal bacteria) is the most common vaginal infection that causes a vaginal odor. Trichomoniasis (STD) also can cause a vaginal odor whereas chlamydia, gonorrhea, and yeast infections generally do not.
