Hmm football season ? Could be from all the sweating and wearing a jock strap. bacteria or yeast can cause itching. bumps could be a result of this or in grown hairs. have you had any unprotected sex/oral? Honestly you should see a doctor for this...if it is just an infection or rash, keeping the area clean and wearing loose clothes will help. Just to be sure, see a doctor.
You need to see a doctor for a proper evaluation and diagnosis. Many things cause bumps and itching. Very few std's present those symptoms. No way for us to tell you what it is or how to treat it. We only provide support and our best guess.
