STI or something else...

Long story short, I believe I got a yeast infection around a year ago.  Treated it with topical ointment and powder sprays and it never seemed to fully go away.  I then thought it was urethitis which I treated with azithromycin 1000mg 1 dose and 500mg/day for 6 days, no change. Tried diflucan 400mg 1 dose and 200mg/day for 6 days, no change.  My current partner was diagnosed with chlamydia and was treated with azithromycin 1000mg single dose.  2 red spots developed on the under side of the shaft and I then went to the ER.  I was given a cephalosporin injection and doxycycline 100mg/twice a day for 10 days.  No change at all still.  I was never actually tested for anything just treated for chalymdia, gonorrhea, and a yeast infection.  I've also tried all kinds of home treatements, hydrocotisone, detox's, etc.. with no luck.  I have no symptoms or discomfort other than the red rashy area that occurs after stimulation.  My penis looks completely normal until bloodflow is increased.  It becomes red with any kind of stimulation.  It is also red when I wake up with a morning erection so I believe the bloodflow causes the redness and not an outside source.  The redness goes away by the next day.  It only becomes red above my circumsion scar/discoloration.  My PCP said that he has no idea and this its possibly a normal change, but I disagree.  I have attatched a picture of my symptoms directly after stimulation.  Any help would be amazing as this has been plaguing my sex life (which was very active) for over a year.

If mild, diffuse redness described by you, and visible on a picture you attached, is triggered by friction, resolves spontaneously after few hours, and no other symptom/discomfort exists, you should not worry because that skin reaction is within physiological range.

In regards to your undiagnosed but treated infections, the only way to get to the bottom of it is to discontinue any sort of topical and/or oral treatment for 3 weeks and then perform diagnostics. In general, it is not recommended to treat clinically inconclusive changes without appropriate diagnostic investigation (starting with taking thorough history of a disease all the way to bacteriology, mycology, histopathology, etc., when indicated).

Yours in optimal health,
