I had oral sex and also sex yesterday night and I noticed a difference in feeling. Today after showering I noticed red spots on the head and inside of my foreskin. Maybe 7 spots in total, 5 of them are very small on the head and 2 of them seemed blotched together but no bigger than a 1/4 inch. Not itchy but when touched felt itchy. Went to get an std test immediately. Throughout the day no itching but toward the night it feels irritated. Spots got a little smaller and grew in other places but not more than 8 so far. Any idea what it is?
