I am continuously suffering from yeast infections.  I am extremely careful about staying clean down there but I am sexually active with my boyfriend of 2 years. We do not use condoms, and occasionally he will finish inside of me. I was wondering if HE could be the cause of my reoccurring yeast infections.
