Welcome to HCM
We understnd your concerns
The available symptoms may not allow us to reach a correct diagnosis. But these symptoms may not be of a sexualy transmitted disese. But these rather correspond to psychological ones arising out of guilty feeling after that unprotected sex. Don't worry. You can always confirm whether you are affected. Please consult a sexologist
for pathological investigation and further advice. Please don't be anxious.
Get well soon.
