I recently received unprotected oral sex from another guy(on Monday night) it is now Friday. I ejaculated in his mouth. The day after I noticed that the head of my penis was red and it was quite sore. My urethane was also sore but this has calmed down a little. I have a very mild burning pain when urinating. It has been red since then but it is not as sore now. My testicles are swollen and sore. I am really quite itchy on and around my genitals and in some other places on my body(not extremely itchy) I come out in a slight rash now and again in my pubic area and on some parts of my body. Any help would be greatly appreciated as I'm worried sick.
