On a good note, i wouldn't worry about it that much, you'd need to have intercoure multiple times with that person to really contract the disease as majority of the time it dies in your urethra track
i think it s irresponsible for you to say that on a forum with loads of young people 
what if you happen to be that one person who contracted it during that first time they had intercourse with an infected person ?
what if people read it wrong an think they cant get infected if it 's their first time ever?
although being hiv positive doenst have to be a death sentence anymore, i reckon most people would avoid contracting it if they were given the choice.
