Bless your precious heart! I am so sorry you are struglling with this.
I know, at least to some extent, how you feel. I'm the highest libido in my house, and sometimes I have to deal with issues like these. I'm sending you a private msg, because I am simultaneouly a lascivious vixen and a demure church lady.
But what I want to point out right away is that if your gf has thrush, everyone in your house needs to take preventative action against candida
overgrowth and infection. I know candida
is "just a yeast" but it can be some NASTY stuff when it's growing in the wrong place.
At the absolute least, I hope you all eat lots of live-culture probiotic yogurt and get educated on candida
