I've Had two first I lost a testacle because of torsion that's a long story. A couple of years ago I had a bad yeast infection on my penis right on the frenulum area in a couple of folds and a couple of ulcers from it on the head never had a small wound that hurt so bad. A couple of the scars still hurt. Had sex with my wife a couple of weeks ago and came down with another a couple of days later. I told her she had a yeast infection and she argued with me. A week or so later she went to the dr's office and told them she had a UTI. They took urine, called the next day and told her she had yeast. At least I knew what it was that time and started treating as soon as I felt the scratchiness. I am parinoid now and have been since the first infection. I usually treat for it everytime for a few days just to make sure.
