I had sexual intercourse with my girlfriend and noticed my right side of scrotum was wet from her.  The same spot began to tighten on the scrotum.  I did not pay much attention until the next day when more of the scrotum began to tighten and as the days went by the entire scrotum tightened with folds.  During ejaculation, the tightening worsens significantly, to the point that the testes are pulled up and almost inside.  A week or two later I began to notice red dots on my scrotum with no itching. 

We were both tested for STDs resulting negative for everything.  She had a Pap Smear and it returned that she had Candida Albicans yeast infection.  I noticed that many many posts credits yeast infection.  I strongly agree because I know my body very well and I know that the tightening initially happened where her wetness was on the right side of my scrotum, and that is where I noticed the scrotum tightening.  Further research of Candida yeast infection in the intestines can cause serious concerns of multiple symptoms such as constipation.  Continued exposure without treatment allows the Candida to take deep root in the intestine and feeds on many types of foods.  Because of the long-term potential exposure, this can result in serious mental problems because of the by product that the Candida produces which the large intestines filters to or from the liver.  Many ways to get Candida in the intestine such as excess drinking, inhalers for athsma, steroids, antibiotics.  All these causes the body become vulnerable to Candida infection.  After a very long period, the Candida can take deep enough root where it penetrates the intestinal walls, which can emit methane gas into the body, which can cause multiple "snowball effects" for different symptoms that are difficult to diagnose, so the problems persist and the snowball effect continues to grow and other symptoms develop.  Many doctors attempt to treat the symptoms because they do not understand the original cause, and the patient's mental frustration worsens.  This happened to me for five years, and my girlfriend's Pap Smear identified Candida, which motivated me to search "Candida" on the internet.  This popped up hundereds of links of many people having many many symptoms, depending on how long they had Candida without being treated.  There is so much more information about Candida and it is too much to put in this forum.  However, this once "small issue" could become a very deep problem such as a doctor diagnosing patients with bipolar.  Yes, this can become so emotional because of the multiple treatments and different byproduct of the Candida's waste getting into the body.  Please do research on Candida if there are unexplained symptoms, because there are many many others that I have not listed.  Thanks to my girlfriend having a yeast infection, allowed me to identify the multiple problems/symptoms over the past five years.  Do not dismiss this tiny problem because it has the potential to grow far beyond what your mental status desires to go.

There are YouTube videos of a very smart DR who wrote a very detailed book about Candida.  It did have a small cost for the downloadable book, but it is over 900 pages of information for many other important topics, as well as the proper diet to destroy the Candida infection.  I believe the book is called "Candida Crusher"  There is also a gentle supliment that can be taken.  Another prescribed medication can be taken, but it is pretty harsh on the liver.  I hope this post can help many people because this simple Candida problem has caused some very difficult situations, and many unfavorable opinions.  God Bless.
