My husband and I have been together for almost a decade. For the past two years, every time we have intercourse, my yeast gives him a yeast infection.  I have changed my diet drastically since then, to see if it would help, but it hasn't. He gets creams prescribed by a doctor that helps, but those get spendy, plus the infection includes a rash that is painful for him. Does anybody have any ideas on how to help with this?
