I think you have contracted a case of Candida. The Vagina of a woman is thriving with Candida when she is Iodine deficient and you caught it.

I suggest you go on the Dr. Brownstein Iodine Protocol to get rid of your Candida, and treat your prostate & testes to the Iodine that they require to produce clean semen. If you have parasites, iodine will kill them, too.

Google "Candida Semen" for a lot of hits.

Next time you date a woman with a stinking vagina, get her started on iodine. This is a very common affliction in women, also called a yeast infection. A healthy vagina is odor free.
