That is venous engorgement, which normally occurs whenever there is an erection, since erection itself is cause by increased blood flow in the penile blood vessels. For the most part, I don't think you need any intervention. However, if you want to be doubly sure, you can consult a urologist to be sure. I personally don't think you have anything to worry about.
