Hello ma'am and welcome.
It is advised to avoid sexual contact in all forms for a duration of at least 2 weeks after the last symptom of the infection is experienced.
As for the yellow discharge, if this is a one time thing then it could be normal. But if at all it recurs, then in my opinion it would be benficial to start application of clotrimazole
preparations in the affected region. Please speak to your doctor regarding the same.
Hope this helps.
