OK so this is a little emabressing.. but I wash everyday and I'm a healthy 20 year old. But lately I can't help but notice my vigaina this smelly fishy kind of smell , even after I wash I can still smell it ? What could it be?

Maybe infection. Go to your gyn.

Is the odor there particularly after intercourse? If so, it is possibly bacterial vaginosis and needs to be properly diagnosed and treated by your doctor.

I'm not sure if you have financial limitations, but you should definitely consult a medical expert as soon as possible.
