I know we don't like it but we gotta look at the possibility that porn will be done with condoms. You can try and be a safe as possible and not use condoms in film but like alot of posts have said you don't know if a performer caught something from having sex with someone between shoots or went to another country and did a shoot with some other 'infected' performers. If the tests don't show a positive result for someone just infected thats a big risk! I guess its a catch 22, we don't wanna see our favorite star get infected but we also don't want her scenes to seem synthetic because of condoms being used
