The past three days my scrotum and penis have been itching like crazy, it is red and inflamed, we (my wife and I) just got a brand new puppy a week ago and I do all of the grooming. When I am at home, I am an Al Bundy with my hands down my shorts while I lounge. I have no STD's before I met my wife and have been faithful. It doesn't look like any poison Ivy nor does it have any white vesicles or any vesicles for that matter. The penis head is not inflamed but the entire shaft and entire scrotum is red, raised a bit and inflamed. I have used campho-phenique and a poison ivy soap, and it is still itching like crazy. What is going on???
They could be bites, or possibly just blocked follicles, which are common in this area. They do not sound like any sort of STD. The best thing to do would be to leave them alone, apply an over-the-counter antibiotic like bacitracin or neosporin daily, and let them go away. If you keep getting new ones, show a doctor, not because they're necessarily serious but because you want to find out what they are.
Best.
