Hello community Im asking a question for myself, an encounter I had on february 25 2019, so last monday. I had protected anal with a transexual and unprotected oral but i wasn't able to go fully inside of her so we just finished with oral. exactly a week after that encounter, march 4, 2019, i noticed a dry patch at the base of my penis but i didn't look at it until wednesday and when i looked it at it then it looked like a red spot. it did not hurt so i chalked it up to dry skin i guess. but i looked at it this morning now it looks really ugly like i can't describe it. so now I'm freaking out that it might be syphilis because it doesn't hurt and I'm unable to get a hold of my primary care provider because he is usually able to talk me down but now I'm freaking out because what if it is syphilis. would it be too soon for the syphilis sore to show up? 7 days after exposure? and would it start out as just a dry patch? please help!
