hello, I m a 26 year old uncircumcised male. I wasn t able to pull my foreskin all the way back until I was about 17, which took some serious effort. When this was done there was some white/yellow stuff under the foreskin, I washed it off and have washed it with soap and water on a regular basis since; however, almost ten years later, if I miss even a few days of washing it while on a camping trip or something, the yeast looking stuff comes back. Is this a yeast infection or what?
Degree understand your concerns went through your description. I suggest you not to worry much. The white and yellowish stuff you are finding around your penis head is simply a mixture of urine, dust, may be some sperm cells and other atmospheric and fabric impurities. The best alternative is to keep the area clean.  If you start worrying about this, the worry might lead you towards anxiety disorders. You might need psychological counseling., I am more than happy to provide telephone psychological counseling through Chat Doctor. Contact me through customer care, www.ChatDoctor .com.
