I (male) had an std test two weeks ago with negative results for hiv, syphilis, chlamidia, and herpes 2. Since then, I have not had sex with anyone until 2 nights ago. I was in Costa Rica on business and had a wild drunken night with friends having sex with 1 gorgeous prostitute, no oral sex, and had a condom on for vaginal sex (there was slight briefly (30 seconds) and softly rubbed genitals with no condom before penetrating as she wanted sex without it but luckily I had the fortitude to demand a condom). Then I had sex with another not so gorgeous prostitute twice, both times receiving brief oral sex without a condom, and both times vaginal sex with a condom.
Regarding my std tests, my healthcare provider indicated that with no discharge, there is no need for gonorrhea tests, how true is this?
Regarding my sex acts, how worried/nervous should I be for hiv, syphilis, chlamidia, gonorrhea, and herpes 2? I feel the most nervous about herpes 2 since I read condoms are only partially effective at prevention. Can you please explain what my chances/risks are, whether you recommend testing without symptoms? Should I not have sex with anyone until a few weeks I take std tests again?
