Hi. i am not oped gay guy and i've just had sex for the first time. should i be worried that i have hiv if he egaculated inside me with a condom on?

Sounds safe: If the condom remained on, you shouldn't be worried. But it's still a good idea to get tested once or twice a year if you 're sexually active. Don't ever have anal sex without a condom, especially when you're the the one on the bottom!

HIV: As long as there was no penetration without the condom the chances are excellent that you are well protected. But do not allow yourself to be exposed orally, anally or otherwise to semen in any form, and that includes so-called pre-cum which can carry the virus.
