I am a 21 year old woman. About two and a half months ago, I had a drunken encounter with a man i met at the bar. We came back to my apartment and started kissing, and then took our clothes off. He got on top of me for a few seconds while we were naked (about 30 seconds), and then I stopped it. There was no penetration, just unprotected contact with his penis (don't know if it was the tip or not) and my vagina for about 30 seconds while he was on top of me. What is my risk for STD's? I have not had any visible symptoms, and I went to a clinic about a month later and got checked for chlamydia and gonorrhea, and they did not find anything. Two months later, I got tested for HIV and it came back negative. Is there a risk of HPV or Herpes from this exposure? Also, can I be sure that I really don't have chlamydia or gonorrhea from this exposure (Is being checked one month later enough time to know for sure?) Thank you for your help!
