thanks guys.. i have sex with someone but im confident she doesn't have STD. maybe i just have 2 see a doctor for proper diagnosis. just hoping someone can enlighten me here. but anyway thanks for your quick response. i thought i would wait for several days to receive comments. anyway thanks again.
you really should see a doctor for a proper diagnosis and before it goes away. They will be able to take a swab if needed if you go while the sore is there. we can't tell you what it is as we can't diagnose you over the internet.
But if you have had unprotected sex then you should consider full STD testing, whether the sore on your penis is related to an STD we are unable to tell you.
see a Dr, this does not sound like a STD at all.
