2 weeks ago I received unprotected oral sex from someone other than my mate. I freaked out and thoroughly cleaned my penis with soap, water and alcohol wipes. The next day I felt stingning and noticed inflammation at the end of my urethra. The inflammation persists now, two weeks later. There's no discharge, although the inflammation causes my penis to drip after urinating. Perhaps it's my imagination, but I have some testicular pain, too. I have some questions:
1. It appears that this could be chlamydia or NGU. Gonorrhea doesn't seem as likely, because there's no pus or colored discharge. What other common bacteria cause NGU?
2. The other person had no visible oral lesions. How likely is it that it could be herpes? Also, would initial herpes infection present with urethritis and no other sores or lesions?
3. I'm being hopeful here, but could the urethritis (even 2 weeks later) be solely due to my overzealous cleaning?
4. Does this at all seem like a syphyllis case presentation?
Many thanks.
