I have unprotected sex with my partner. I have candida and he does not. Here at Curezone when I previously posted saying that and concluding taht therefore it was safe, other members replied that in their case it was very different and their partner had contracted it.
Having unprotected sex never had major consequences on my yeast infection, but then again, my partner does not have candida, I wonder if it would be any different if he had it.
In your case, since you have contracted it, it would be better to avoid passing it on to one another and make sure you use the condom.
