sorry for my english, well this is my situation, 2 weeks ago I practiced oral sex to an unknown man for like 2 minutes or less, I didn't have contact with his semen but I'm pretty sure I had contact with his pre-***, I don't have any problem in my mouth just caries but I don't have any problems with my gums, there's a pottencial risk that I may have been infected? I'm 20 and I'm a boy, I'm terrified, sorry I hope you can understand me.
After that I spit a lot of saliva that I accumulate in my mouth.
It's in Spanish and has a lot of information about the transmission of HIV (VIH in Spanish). You can scroll down to the section on sexo boca-pene (fellatio) to read about your situation. While it's *theoretically* possible to transmit HIV this way, it's extremely unlikely. It's perfectly possible to get another STI though, like gonorrhea, chlamydia, or herpes, so you should get tested for those. And anal sex without protection is risky, so make sure to use condoms every time. (Aunque recibir el sexo oral sin eyaculación tiene poco riesgo de contratar VIH, ex sexo anal sin duda tiene riesgo de transmitir VIH, y tenga que usar condones cada vez).
Puedes enviarme preguntas en español y voy a tratar de contestarlas o encontrar la información necesario.
