Received unprotected oral / protected vaginal with CSW in the Carribean on 2/23.  3 days later, felt urethral irritation and slight white discharge.  On 3/3 tested negative for Chldya/Gonn but WBC found on swab test.  Prescribed doxy for 7 days.  I still have urethral irritation.  Assuming it's NGU.  I have a regular partner, and avoiding sex until I figure this out.  When can I resume relations?  Would the doxy not clear up any infection going on?

What you describe certainly sounds like non-chlamydial NGU.  This is thought to occur when a partner's oral bacteria enter the penile urethra and, being not normally there, cause irritation.  Non-chlamydial NGU typically resolves with therapy using either doxycycline, 100 mg twice daily for a week or a single 2 gram dose of azithromycin but is not considered to be something that need to require treatment of partners.  The irritation may take a few days to improve.  EWH---

Thank you doctor EWH. 

Could you describe your persisting symptoms?  Is the discharge still present or just the discomfort.  ---

Urethral irritation and slight white discharge especially in the morning.  Feels irritated throughout the day and stringy matter floating in urine.

No pain during peeing - just feel irritation

Thanks.  It may be that what you are detecting is normal sensations and normal urethral secretions.  This is not uncommon for persons who experienced  symptoms and they are on the "lookout".  There is a tendency to amplify findings which might well be overlooked if there had not been an earlier problems.  ---

Thanks doctor.  Much appreciated.

You're welcome.  EWH---
