Hello, I had a sexual contact on August 29. Unprotected genital rubbing. As far as I understand, this does not pose a risk for HIV. However, 3 days after the contact, penile pain started, it's been 10 days today and it still continues. Also, last night, I think the upper part of my anus is the rectal region. Rectal pain started. Is there such a std? My symptoms are penile pain and rectal pain. Also a feeling of pressure like pooping in the rectal area. Tickling sensation in the penis and rectal area. It's like feeling aroused. No discharge or burning sensation. Burning after masturbation. My penis is circumcised. Today, on day 10, I have a chancre formation on my foreskin under the head of my penis. Skin color that looks like a crater. There is a small whiteness in it, which is under the skin. No swelling. I googled the photos but it doesn't look like much. Is this how the chancre starts? I'm not sure. I have a few questions.
1-) Syphilis or chancre cause pain in the penis?
2-) Can chancre come out in 10 days?
3-) Along with penile pain, there was pain in the upper part of the anus last night. Like the feeling of pooping. What can cause both penile and rectal pain? Is this a std ?
4-) I have a std panel test done on day 5. All negative. How safe is it?
5-) If there is any STD transmission in sexual contact, the chance of HIV infection increase in the same contact? During same sexual contact.
Are there any std in these symptoms? Or what could be causing these pains and symptoms? Please help.
