Hi. I did unprotected oral sex and protected sex for an hour. I took a HIV test after 3 months and it came back negative. I didn't take any std tests. I now afraid that I have an stds. I have jock itch at the side of my testicles while doing the intercourse. But I am afraid I may have get syphilis. I don't know what is the risk. I hope you can help me. Should you recommend testing for std? I have already tested for HIV after 3 monthsxand came back negative. Thanks
