This is why your p.r.i.v.a.t.e parts smell like rotten fish

If someone notices a “rotten fish” smell from their intimate area, the most common explanation (especially for people with a vagina) is bacterial vaginosis (BV).

Here’s a clear, non-judgmental breakdown:

What usually causes a fishy smell?

• Bacterial vaginosis (BV):
  This happens when the natural balance of vaginal bacteria is disrupted. The odor is often stronger:

  • after sex

  • during or after a period

• Poor hygiene or trapped moisture:
  Sweat + tight clothing can worsen odors (more common with external genitalia).

• Sexually transmitted infections (STIs):
  Some STIs can cause unusual smells, though BV is far more common.

• Forgotten tampon or foreign object:
  This can cause a very strong, foul smell and needs prompt medical attention.
