I went through a stressful divorce about 15 years ago. My ex was seeing several sex partners. She mentioned she had been checked for STDs and only possibly candida, so I assume that is it.
I didn't have any recognizable symptoms at the time. However after meeting, dating and marrying my 2nd wife: We both developed a skin condition. I had splotches of scaly skin develop on my lower legs which spread quickly up the legs and then the entire penis developed a scaly outer layer of skin that peeled off. I still have small spot of skin on the penis that is extra sensitive as though it was thin.
Next, I had an eyelid that started peeling. That went away.
My wife developed a patch of skin about 6 cm. diameter next to the pubic area on her thigh. She still has problems occasionally with an eyelid the sheds a layer of skin. It can itch and if you mess with it too much it gets sore.
She also has a yellowish vaginal discharge. Not a foul odor, but def a musty type odor.
Now I have a couple less that 1 cm spots on each side of my chin that don't heal, but have a thin layer of dry skin that can be peeled away with a fingernail. Also in the fold behind one of my ears, there is scaly skin that sometimes peels away.
