A vaginal yeast infection can cause itching and redness of the vaginal area (vulvitis candidomycetica). A vaginal yeast infection is not considered as a sexual transmitted disease (STD) because yeasts are normally present in the vagina. In certain circumstances when local immunity gets weaker, the normally present yeasts start to multiply and cause infection and inflammation. Conditions that convey yeast infection to show up are pregnancy, prolonged usage of large-spectral antibiotics, immunity disorders, etc.

A yeast infection can also be stimulated if larger amounts of yeasts are imported from outside. This means that oral sex could theoretically make circumstances for a yeast infection occurring higher.

A microbiological smear and PAP test could show if there is something else besides a yeast infection. You could consult a gynecologist about this.
