Thanks for your question. It is hard for me to understand exactly what it is that you are describing. There are many different problems that can affect the penis and the foreskin, ranging from infections to growths to more common concerns that can involve hygiene and even skin changes that can be normal. Each of these require assistance from a doctor
if the changes fail to resolve in a timely fashion, as some of them can be serious or can be a sign of something else that is happening in your body. Please speak with your doctor about this and other questions so that you can get the answers that you need to be healthy.
