Not an STD: Dehydration would not do this. STDs must be on your mind, by your topic tags. But it doesn't sound like any STD. Intermittent symptoms ("random", "off and on") often are psychological. Most penile skin problems are standard dermatology problems that can occur anywhere but happen to involve the penis. But best to see a doctor at a time you're having symptoms; better safe than sorry. Good luck!
