Hello from Indonesia :),
I really concern about the sore on my penis right now.
On 23rd July, I had anal and oral sex with someone (Im top and using condom while anal sex except oral). While he oral me, his teeth accidently scratch on a part of my penis.
On 24th July, that part turn red and made me feel itchy at the time. I usually swabbed slowly on it with my finger
On 26th july, from red and itchy, it turns a painless sore (sometimes it still a little bit itchy on it). At the time, I consult with my doctor about it. He took a gram test and she said if there some bacteria on that part. But she can't classified which one of bacteria of it. My doctor gived me fussidic 2% for swab on my sore. And he recommend me for take a test of VDRL and HPTA
On July 27th, some part of the sore turn to dead skin (I think)
On 28th July (Actually yesterday), I took a test of VDRL and HPTA. Both are negative. But my doctor said to test again for the next 5 weeks. (I know if it to soon too for the ensurity of both test)
On 29th july, (right now) some part of that dead skin on my sore just falling of while I shower and swabbed with soap. After it, that part like turn to heal it self and make a new skin with some of slight red colour (even not all of it).
Until now, I still use that fussidic.
I have a plan to test of full std next month.
2 months ago, I tested of vct and syphilis. Both are negative.

My question
1. How big the probability if the indication of the sore on my penis is a chancre of syphilis? Because it occurs just 3 days after that activity and the like dry up it self, I can't ensure of it.
2. When someone got a chancre of syphilis, is it a big probability for the test of VDRL and HPTA give the positive result?
