STDs that could be acquired by receiving oral sex are gonorrhea, nongonococcal urethritis (NGU), herpes due to HSV-1, and (rarely) syphilis. If you don't develop penile discharge within 2 weeks or penile sores within 6 weeks, you can safely assume you weren't infected. But if in doubt, you can get tested, e.g. at your nearest health department clinic.
Thank a lot, it was with a street prostitute and we didn't have intercourse. I don't do this regularly but I acted out of impulse.
I'm very relieved to hear that the risk is low, but to what stds could I have exposed myself to? I wanna know so I can detects signs in case something develops.
Cheers
Welcome to the forum.
The risk of STDs is generally low from oral sex, but not zero. However, there are no data on whether this exposure carries any higher risk than it would without the piercing. If the piercing was not recent and all tissues have completely healed, and if the piercing is such that the area would not be injured during sex, I imagine it has no effect on risk.
Although the practice itself (oral sex) is low risk, it sounds like this was a furtive completely anonymous exposure to someone you don't know (I'm impressed by the dramatic "under the shadows" comment). This marks both you and your transsexual partner as persons at very high risk for STDs, including HIV. All such persons should have routine STD and HIV testing from time to time, at least once a year and maybe more often. On that basis, perhaps this is a good time for you to visit your local health department STD clinic for testing -- but not strictly because of this particular encounter.
Of course if you develop symptoms, like penile discharge or sores, or irritation/inflammation of the pierced site, of course get examined right away.
Good luck-- HHH, MD
