Okay, So... Not a BIG deal.
But once upon a time I had a yeast infection.
No symptoms, I was in the pre-infected stages and passed it onto my bf at the time. So it's obviously contageous. It goes away as easily as it comes, it's like a common cold.
But his cum was brownish-looking, he had teeny-weeny little boils and it burned when he peed.
It lasted about 3-4 days and then he was fine. Woo - that was embarrassing to admit. Anyway,
If it sounds similar, just by a yeast infection cream and apply to the infection.
