Why is it that every single time after sexual intercourse my discharge frequency changes including the smell?

Vaginal discharge. Bacterial presence in the vagina can exist without producing a discharge or odor until intercourse provides a way to enable evidence to spread over the vaginal area and be detectable. On the other hand, sex with a partner who has other female partners may give you infections which can cause both discharge and odor. Consult your healthcare provider for tests.
