Hi there Gloria. Hi there. Yeast infection does not necessarily constitute an STD. More often than not, it is just a fungal infection. Perhaps you should consider getting your boyfriend treated at the same time (assuming he is the same boyfriend). Also if he has insurance, the doctor could legally & ethically prescribe diflucan or any other medication in sufficient quantities to treat both partners . please do check on this..dont take my word for it. Again, possibly you are getting reinfected from the fomites..so do treat all the undergarments, clothing, sheets, towels etc (both partners) as per requisites with hot water & dry well in the sun for a day or two. Sunlight is a good antifungal! It is also possible you could do with some immune supplements as a low immune status could predispose to repeated fungal infections. Do put yourself on an antoxidant tab once/day for a month. Wish you good sexual health & do practice safe sex. Cheers !
