First off I would like to say thank you for taking time to read my question. Just recently about 3 days ago I gave unprotected oral sex to another man I did not know the man at all and I did get ejaculate in my mouth, I am extremely worried about stds HIV in particular! He did not seem to have any sores and looked clean, but I am still very worried about the risks! Should I be tested how high is the risk? Thank you for all answers!
